  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments described below, members that are common to each other are denoted by the same reference numerals, and duplicate descriptions thereof are omitted.

  FIG. 1 is a perspective view showing an external configuration of a gaming machine 1 according to an embodiment of the present invention, and is a view of the front side of the gaming machine 1 as viewed obliquely from below. The gaming machine 1 according to the present embodiment includes a main body frame 2 fixed to an island facility of a hall (store) and a front frame member 3 provided on the front side of the main body frame 2. The front frame member 3 is pivotally supported by a support portion 2a, 2b provided at the left end portion of the main body frame 2 so as to be openable and closable around a predetermined vertical axis. Further, the front frame member 3 has a window portion 5 in which a transparent plate unit 4 is fitted in the center thereof so that the game area 21 of the game board 20 (see FIG. 11) provided inside the main body frame 2 is visible. Have.

  Further, the front frame member 3 has a ball receiving portion 6 formed in a state of projecting to the front side of the gaming machine 1 below the window portion 5. On the upper surface of the ball receiving portion 6, a ball receiving tray formed in a concave shape for receiving a prize ball paid out from the gaming machine 1 is provided. Further, on the upper surface of the ball receiving portion 6, an effect button or the like not shown is provided. A handle lever 7 operated by the player is provided at the lower right portion of the ball receiving portion 6. When the player rotates the handle lever 7 clockwise, the game ball launching mechanism is activated, and the game ball is launched into the game area 21 of the game board 20 at a predetermined time interval with the hitting force according to the operation angle. It is. When the game ball enters the various winning holes provided on the game board 20, the corresponding prize ball is paid out to the ball tray.

  The front frame member 3 includes a frame lamp 11 in which a plurality of LEDs and the like are arranged in the vertical direction on the left and right sides of the window portion 5. The front frame member 3 has a bulging portion 3a with the upper portion protruding to the front side, and a pair of speakers 10 are provided on the left and right sides of the bulging portion 3a. An upper lamp 12 is provided. The upper lamp 12 can produce an effect according to the progress of the game, so that the light irradiation direction can be swung in the vertical direction or the horizontal direction. It is provided inside. Further, the front frame member 3 is a bulging portion 3b projecting to the front side also below the ball receiving portion 6, and a lower lamp 13 which is a kind of frame lamp is provided at the center of the bulging portion 3b. . Since the lower lamp 13 also produces an effect according to the progress of the game, the light irradiation direction can be swung in the vertical direction or the horizontal direction, and the drive mechanism thereof is the bulging portion 3b. Is provided inside.

  As shown in FIG. 1, a plurality of distance sensors 9 a and 9 b are provided as distance measuring means 9 on the lower surface side of the bulging portion 3 a provided on the upper part of the front frame member 3. In the present embodiment, as shown mainly in FIG. 1, a case where two distance sensors 9 a and 9 b are provided at different positions in the bulging portion 3 a of the front frame member 3 is exemplified, but the number of distance sensors is three. It may be above. Further, in the present embodiment, these distance sensors 9a and 9b are not strictly located at the front frame member 3, but are provided above the transparent plate unit 4 as described later. Then, the transparent plate unit 4 is attached to the window portion 5 from the back side of the front frame member 3, so that the upper portion of the transparent plate unit 4 is integrated with the upper portion of the front frame member 3 so that a part of the bulging portion 3 a is formed. As a result, the distance sensors 9a and 9b are attached to the lower portion of the bulging portion 3a.

  The distance sensors 9a and 9b detect an object existing near the surface of the transparent plate unit 4, and measure the distance to the object. These two distance sensors 9a and 9b are provided at symmetrical positions in the bulging portion 3a, and the main body bulges at a position on the front side (side where the player is located) from the surface of the transparent plate 40 described later. It is held inside the part 3a. The distance sensors 9a and 9b are attached so as to face the space on the surface side of the transparent plate unit 4 from the lower surface of the bulging portion 3a, and each sensor independently reaches an object existing near the surface of the transparent plate unit 4. Measure distance without contact. An object to be measured by the distance sensors 9a and 9b is, for example, a player's hand. As such distance sensors 9a and 9b, for example, a non-contact type sensor such as an ultrasonic sensor or an optical sensor can be used. In the present embodiment, an example in which an ultrasonic sensor is employed is exemplified.

  Further, as shown by a broken line in FIG. 1, a coil 8 for detecting an illegal act by a magnet is provided at the peripheral edge of the transparent plate unit 4. When the coil 8 moves in a direction in which the magnet approaches or separates from the transparent plate unit 4, the coil 8 is wound a predetermined number of times along the peripheral edge of the window portion 5 so as to generate a relatively large induced electromotive force. Arranged in a rotated state. A specific arrangement form of the coil 8 will be described later.

  Next, FIG. 2 is a diagram showing a detailed configuration example of the distance sensors 9a and 9b which are the distance measuring means 9. As shown in FIG. Each of the distance sensors 9 a and 9 b includes a flat base member 14, an ultrasonic transmitter 15 provided substantially at the center of the base member 14, and two ultrasonic sensors provided at symmetrical positions across the ultrasonic transmitter 15. Sound wave receivers 16 and 17 are provided. For example, the ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 are each configured by the same piezoelectric element.

  The ultrasonic transmitter 15 sends an ultrasonic wave corresponding to the frequency of the pulse voltage from the surface 15a of the element by applying a pulse voltage of a predetermined frequency (for example, 40 kHz) to the piezoelectric body having a laminated structure. At this time, the ultrasonic transmitter 15 transmits an ultrasonic wave within a predetermined angle θ with reference to the central axis of the piezoelectric element. This angle θ can be appropriately set by changing the piezoelectric element to be used. In this embodiment, the transparent plate unit 4 is provided from the lower surface side of the bulging portion 3a of the front frame member 3. It is preferable to set so that almost the entire area is within the ultrasonic wave transmission range.

  The ultrasonic receivers 16 and 17 are for receiving the reflected wave reflected by the ultrasonic wave transmitted from the ultrasonic transmitter 15 when it hits an object in the vicinity of the surface of the transparent plate unit 4. When ultrasonic waves are incident on the surfaces 16a and 17a of the ultrasonic receivers 16 and 17, the piezoelectric body having a laminated structure vibrates accordingly. Therefore, each ultrasonic receiver 16 and 17 corresponds to the frequency of the received ultrasonic waves. Generate a pulse signal (voltage). As will be described later, an object located near the surface of the transparent plate unit 4 due to the time difference between the timing at which the ultrasonic transmitter 15 transmits the ultrasonic waves and the timing at which the ultrasonic receivers 16 and 17 receive the ultrasonic waves. Configured to measure the distance to.

  Here, since each ultrasonic receiver 16, 17 is the same piezoelectric element as the ultrasonic transmitter 15, the ultrasonic incident angle range in which each ultrasonic receiver 16, 17 is sensitive is the ultrasonic transmitter 15. Is substantially the same as the sending angle θ. Therefore, as shown in FIG. 2, by providing the two ultrasonic receivers 16 and 17 at symmetrical positions with the ultrasonic transmitter 15 as the center, a receivable area of the reflected wave in these arrangement directions is provided. The reflected wave reflected from the reach of the ultrasonic wave transmitted from the ultrasonic transmitter 15 can be detected without omission.

  The distance sensors 9a and 9b having the above-described configuration are arranged so that the arrangement direction of the ultrasonic receiver 16, the ultrasonic transmitter 15, and the ultrasonic receiver 17 is substantially parallel to the surface of the transparent plate unit 4, as shown in FIG. Is provided. Therefore, the ultrasonic wave receivable areas by the two ultrasonic receivers 16 and 17 extend in a direction substantially parallel to the surface of the transparent plate unit 4, and the ultrasonic transmitter 15 near the surface of the transparent plate unit 4. It is possible to receive the reflected wave reflected from the transmission range of the ultrasonic wave without leakage.

  In addition, in the above, the case where the ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 were comprised with the same piezoelectric element was illustrated. By configuring these with the same piezoelectric element, it is possible to reduce the types of parts, so there is an advantage that the cost can be suppressed, but it is not necessarily limited to configuring them with the same piezoelectric element. is not. For example, if an ultrasonic receiver having sensitivity in an incident angle range wider than the angle range θ in which ultrasonic waves are transmitted by the ultrasonic transmitter is used, the number of ultrasonic receivers provided in each distance sensor is one. be able to.

  FIG. 3 is a schematic longitudinal sectional view of the upper part of the gaming machine showing the attachment state of the distance sensor 9a. It should be noted that the mounting state of the distance sensor 9b is the same as this. As shown in FIG. 3, the distance sensor 9 a is fixed to a predetermined location inside the bulging portion 3 a that is formed to protrude from the upper portion of the front frame member 3, more specifically, inside the upper portion of the transparent plate unit 4. . That is, the upper part of the transparent plate unit 4 has a protruding portion 43b that is thicker than other portions and protrudes to the front side, and the distance sensor 9a is held inside the protruding portion 43b. ing. When the transparent plate unit 4 is attached to the window portion 5, the lower surface of the overhang portion 43b is substantially flush with the lower surface 3c of the bulge portion 3a, and a distance sensor 9a is provided on the lower surface of the overhang portion 43b. Three holes 18 are provided corresponding to the positions. The ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 of the distance sensor 9a are disposed in the three holes 18, and the respective surfaces 15a, 16a and 17a are substantially flush with the lower surface 3c of the bulging portion 3a. It is attached to become the state. Therefore, even when the gaming machine 1 is viewed from the front, the distance sensor 9a is inconspicuously attached.

  Further, as shown in FIG. 3, the axial direction (piezoelectric element stacking direction) of the ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 of the distance sensor 9a is substantially parallel to the transparent plate 40 of the transparent plate unit 4 in a side view. It is. Therefore, the distance sensor 9 a sends out ultrasonic waves along the surface of the transparent plate unit 4.

  Further, as shown in FIG. 1, the distance sensors 9a and 9b are arranged so that the axial directions of the ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 are in front so as to send ultrasonic waves toward the central portion of the transparent plate unit 4. It is in a state slightly inclined in the left-right direction when viewed. Therefore, each distance sensor 9a, 9b can transmit an ultrasonic wave toward almost the entire surface of the transparent plate unit 4, and can detect an object at an arbitrary position near the surface of the transparent plate unit 4. Can do.

  Here, the configuration of the transparent plate unit 4 will be described. As shown in FIG. 3, the transparent plate unit 4 includes a transparent plate 40 that allows the game board 20 held by the main body frame 2 to be visually recognized from the front side where the player is located, and a peripheral portion of the transparent plate 40. And a holding portion 43 provided. The transparent plate 40 is configured to include two transparent glass plates 41 and 42 disposed at a predetermined interval in the front-rear direction on the front side of the game board 20. Among these, the 1st transparent glass plate 41 is a transparent glass plate located in the player side during a game. The second transparent glass plate 42 is a transparent glass plate located on the game board 20 side during the game. The holding | maintenance part 43 hold | maintains those peripheral parts so that these two transparent glass plates 41 and 42 may be in the parallel state which separated predetermined spacing. A coil 8 is laid on the holding portion 43. As shown in FIG. 3, the transparent plate unit 4 is fixed to the window portion 5 of the front frame member 3 while being fitted from the back side of the front frame member 3.

  FIG. 4 is a perspective view of a state in which a part of the transparent plate unit 4 is cut in order to explain the detailed configuration of the transparent plate unit 4. FIG. 4 is a view of the transparent plate unit 4 as viewed obliquely from the front side. As shown in FIG. 4, the holding portion 43 of the transparent plate unit 4 is an annular member provided along the peripheral edge portion of the transparent plate 40. The holding portion 43 is formed so that the portions holding the side portions and the lower portions of the two transparent glass plates 41 and 42 are formed relatively thin, and the upper portion is relatively thick and the front direction in which the player is located (see FIG. A projecting portion 43b projecting in the middle X direction side). The projecting portion 43b is hollow inside, and two distance sensors 9a and 9b are provided in the hollow space, and various signal processing circuits for controlling the coil 8 and the distance sensors 9a and 9b are mounted. A sensor control board 300 is provided. A connector 45 that is electrically connected to the sensor control board 300 is provided on the front side of the overhang portion 43b.

  Further, on the upper portion of the holding portion 43, flange portions 44 for fixing the transparent plate unit 4 to the front frame member 3 are provided at two predetermined positions on the left and right.

  Further, as indicated by a broken line in FIG. 4, the coil 8 is provided between the two transparent glass plates 41 and 42 and is wound a predetermined number of times along an annular holding portion 43 that holds the transparent plate 40. Is arranged in. The coil 8 is for detecting magnetism in the vicinity of the front of the game board 20, but does not have a movable part (open / close switch) like the conventional reed switch type magnetic sensor. Even when an impact or the like is applied to the surface, it is difficult to break and stable magnetic detection can be performed.

  FIG. 5 is a partially enlarged cross-sectional view showing two arrangement examples of the coil 8 in the transparent plate unit 4. Each of FIGS. 5A and 5B corresponds to an enlarged view of the portion A shown in FIG. The holding portion 43 that holds the peripheral edge portions of the two transparent glass plates 41 and 42 enters between the two transparent glass plates 41 and 42 in order to hold the interval between the transparent glass plates 41 and 42 at a predetermined interval. It has the spacer part 43a located in the state which carried out. The spacer portion 43 a is provided over the entire periphery of the transparent glass plates 41 and 42.

  In the arrangement example of FIG. 5A, a concave groove 46 is formed on the surface of the spacer portion 43 a of the holding portion 43 facing the second transparent glass plate 42, and the coil 8 is arranged in the concave groove 46. Since the concave groove 46 is an annular groove formed along the periphery of the transparent glass plates 41 and 42, by winding the coil 8 along the concave groove 46, substantially the entire transparent glass plates 41 and 42 are formed. The region can be stored inside the coil 8. And as shown to Fig.5 (a), by providing the ditch | groove 46 in the surface facing the 2nd transparent glass plate 42 of the spacer part 43a, the gaming state (with the transparent plate unit 4 mounted to the front frame member 3 ( In the state shown in FIG. 1, it can be arranged so that the player cannot visually recognize the coil 8. Further, in the arrangement example shown in FIG. 5A, the coil 8 is provided between the first transparent glass plate 41 and the second transparent glass plate 42, and thus is protected by the transparent glass plates 41 and 42. It is in a state. Therefore, for example, the coil 8 can be prevented from being cut by a malicious player or the like. 5A illustrates the case where the concave groove 46 is formed on the surface of the spacer portion 43a facing the second transparent glass plate 42, the surface on the opposite side, that is, the first surface. A concave groove 46 may be formed on the surface facing the transparent glass plate 41 and the coil 8 may be disposed there.

  Further, in the arrangement example of FIG. 5B, the coil 8 is arranged along the distal end portion of the spacer portion 43 a of the holding portion 43. Since the holding portion 43 is an annular member that holds the peripheral portions of the two transparent glass plates 41 and 42, the winding of the coil 8 along the distal end portion of the spacer portion 43 a allows the abbreviation of the transparent glass plates 41 and 42. The entire region can be stored inside the coil 8. And the coil 8 can be arrange | positioned, without reducing the visibility of the game board 20 by fixing the coil 8 to the front-end | tip part of the spacer part 43a with an adhesive agent. A concave groove similar to the above may be provided at the tip of the spacer 43a, and the coil 8 may be disposed there. 5B, the coil 8 is provided between the two transparent glass plates 41 and 42, so that the coil 8 is protected by the transparent glass plates 41 and 42. Therefore, for example, the coil 8 can be prevented from being cut by a malicious player or the like.

  Of the two arrangement examples shown in FIGS. 5A and 5B, which one is adopted is arbitrary. Moreover, it is good also as an arrangement | positioning form different from the arrangement example mentioned above.

  FIG. 6 is a diagram illustrating a configuration example of the coil 8. The coil 8 is configured by, for example, a cable CB having a plurality of core wires 8a to 8h. The cable CB has a diameter that can be accommodated in, for example, a concave groove 46 provided in the holding portion 43 of the transparent plate unit 4, and a plurality of core wires 8 a to 8 h that are accommodated inside thereof are each provided with an insulating coating. The core wires 8a to 8h are independent conducting wires. Such a cable CB is cut according to the length of the portion where the coil 8 is laid (for example, the length of the concave groove 46 constituting the annular groove), and the core wires 8a to 8h appearing at both ends thereof are shown in FIG. In this way, the coils 8 having the number of turns corresponding to the number of core wires are configured. The core wire 8a appearing at one end portion of the cable CB and the core wire 8h appearing at the other end portion are not connected to any core wire, and become both end portions of the coil 8. That is, when a magnetic flux change occurs in the coil 8, the induced electromotive force appears between the core wire 8a at one end of the cable CB and the core wire 8h at the other end. The core wires 8a and 8h that are both ends of the coil 8 are connected to the sensor control board 300, respectively. In the case of the illustrated example, since the number of core wires is 8, the number of turns of the coil 8 is 8, but this is not necessarily limited to this. Further, the configuration of the coil 8 described above is an example and is not necessarily limited thereto, and a coil 8 different from the above configuration may be employed.

  FIG. 7 is an enlarged cross-sectional view showing a portion where the connector 45 is provided in the transparent plate unit 4. The connector 45 includes an electrode 45 a that is electrically connected to the sensor control board 300. For example, the connector 45 is directly attached to the sensor control board 300 fixed inside the overhang portion 43b. And the connector 45 is attached in the state which faces the front side of the overhang | projection part 43b, as shown in FIG.

  Further, the sensor control board 300 is connected to the coil 8 provided in the spacer part 43a and distance sensors 9a and 9b provided inside the overhang part 43b. Each of the sensors 9a and 9b is individually controlled. Here, each of the conducting wire that connects the coil 8 and the sensor control board 300 and the conducting wire that connects the distance sensors 9a and 9b and the sensor control board 300 are wired inside the projecting portion 43b. Therefore, it has a structure that can prevent those conductors from being intentionally cut.

  Next, FIG. 8 is a view showing a mode in which the transparent plate unit 4 is attached to the window portion 5 of the front frame member 3. The front frame member 3 includes a locking member 47 for fixing the transparent plate unit 4 to a plurality of peripheral edge portions of the window portion 5 on the back surface side. Among the plurality of locking members 47, those provided at two upper portions of the window portion 5 are provided at positions corresponding to the flange portions 44 of the transparent plate unit 4. A locking member 47 is also provided at the lower right portion of the window portion 5. When the transparent plate unit 4 is fitted into the window portion 5 and attached, for example, as shown in FIG. 8, each of the plurality of locking members 47 is rotated in the R direction, and the transparent plate unit 4 is moved forward in that state. The frame member 3 is fitted into the window portion 5 from the back side. Then, after the transparent plate unit 4 is fitted into the window portion 5, the plurality of locking members 47 are rotated in the direction opposite to the R direction, whereby each locking member 47 is engaged with the peripheral portion of the transparent plate unit 4. The transparent plate unit 4 can be fixed together. Each locking member 47 may be provided with a biasing means such as a spring so as to press and bias the transparent plate unit 4 against the front frame member 3.

  Further, the upper portion of the window portion of the front frame member 3 has a recessed shape corresponding to the shape of the protruding portion 43 b of the transparent plate unit 4, and the protruding portion 43 b of the transparent plate unit 4 is formed at the center thereof. A connector 48 is provided as a pair of the connector 45 provided in FIG. For example, if the connector 45 is a male connector, the connector 48 is a female connector paired therewith. The connector 48 includes an electrode 49 for electrical connection with the sensor control board 300. When the transparent plate unit 4 is attached to the front frame member 3, the connector 45 of the transparent plate unit 4 is in a state of being connected to the connector 48 provided at the upper part of the window portion of the front frame member 3.

  That is, the connector 48 provided on the front frame member 3 is in a position corresponding to the connector 45 provided on the transparent plate unit 4, and the transparent plate unit 4 is attached to the back side of the front frame member 3 as shown in FIG. 9. The connector 45 of the transparent plate unit 4 and the connector 48 of the front frame member 3 are connected to each other by being fitted into the window portion 5 as indicated by an arrow X, and as a result, provided in the connector 45. The electrode 45a and the electrode 49 provided on the connector 48 are brought into contact with each other, and the sensor control board 300 and a signal line (not shown) provided on the front frame member 3 are conducted.

  As described above, in this embodiment, when the transparent plate unit 4 is attached to the front frame member 3, the connectors 45 and 48 are connected to each other, and the sensor control board 300 provided inside the overhanging portion 43b is played. Since it is electrically connected to the machine 1, it is not necessary to separately perform work for connecting the connectors 45 and 48. Therefore, each of the electrical elements (that is, the distance sensors 9a and 9b, the coil 8, and the sensor control board 300) provided in the transparent plate unit 4 can be reliably connected to the gaming machine 1. At the same time, there is an advantage that the mounting operation and the replacement operation of the transparent plate unit 4 can be performed efficiently. When the transparent plate unit 4 is attached to the front frame member 3 as described above, a player who is playing the game cannot directly touch the coil 8, the sensor control board 300, or the like.

  FIG. 10 is a view showing a state where the front frame member 3 of the gaming machine 1 is opened. When the player plays a game, the front frame member 3 is closed by the main body frame 2 and locked as shown in FIG. On the other hand, for example, when a ball clogging occurs in the game area 21 of the game board 20 during the game, the store clerk unlocks the front frame member 3 and opens the front frame member 3 as shown in FIG. Ball clogging can be eliminated.

  As shown in FIG. 10, the transparent plate unit 4 is fixed in a state of being pressed against the front frame member 3 by a plurality of locking members 47. Therefore, when the transparent plate unit 4 is fixed in a state where it is fitted in the window portion 5, the peripheral edge portion of the transparent plate unit 4 and the front frame member 3 are in close contact with each other, and the player hits the transparent plate unit 4 temporarily. However, no rattling occurs. Further, even if the opening / closing operation of the front frame member 3 is repeatedly performed, the transparent plate unit 4 does not fall off the front frame member 3.

  In this state, as described above, the connector 45 provided on the transparent plate unit 4 and the connector 48 provided on the front frame member 3 are connected to each other. The sensor control board 300 provided on the upper part of the transparent plate unit 4 is connected to the cable 19 via the connectors 45 and 48. The cable 19 is wired from the front frame member 3 toward the main body frame 2, and connects the sensor control board 300 provided in the transparent plate unit 4 to a control mechanism described later. As shown in FIG. 10, the cable 19 is wired near the rotation shaft of the front frame member 3 above the window portion 5 and guided from the front frame member 3 to the inside of the main body frame 2.

  In this way, the cable 19 connected to the sensor control board 300 is routed to the hinge side of the front frame member 3 (that is, the vicinity of the rotation axis of the front frame member 3 defined by the support portions 2a and 2b), and the main body frame 2 The wiring of the cable 19 can be installed so as not to stand out. Further, as described above, since the front frame member 3 may be opened and closed by a store clerk during the game, the cable 19 is routed near the rotation axis of the front frame member 3 and wired. 19 does not hinder the opening / closing operation of the front frame member 3. Conversely, even when the opening / closing operation of the front frame member 3 is performed, a load is not applied to the cable 19 and it is possible to prevent problems such as disconnection.

  Next, an example of the gaming board 20 provided inside the main body frame 2 of the gaming machine 1 will be described. FIG. 11 is a front view showing an example of the game board 20. As shown in FIG. 11, the game board 20 has a substantially circular game area 21 surrounded by an outer rail 22 and an inner rail 23. A game ball that is launched when the player operates the handle lever 7 is launched into the game area 21 from a gap between the outer rail 22 and the inner rail 23 provided on the left side of the game area 21. An image display unit 24 is provided inside the game area 21 so as to be positioned approximately at the center of the game board 20. The image display unit 24 is fitted into a through hole formed at substantially the center of the game board 20, and is fixed to the game board 20 by a fixing means such as a screw.

  The image display unit 24 includes an image display 25 including a liquid crystal display at the center. The image display 25 displays effect images for performing various effects as the game progresses, notification images for performing various notifications to the player regardless of the progress of the game, and the like. Further, the image display unit 24 includes various board lamps for presentation and movable accessories arranged around the image display 25.

  The game area 21 is provided with known members such as a large number of nails, through gates, windmills, various winning holes, and out holes arranged around the image display unit 24. Therefore, the game ball launched into the game area 21 rolls downward in the game area 21 while changing the course by a number of nails and windmills, passes through the through gate, and enters various winning holes. It is balled or discharged from the outlet.

  In the case of the illustrated example, a through gate 29 is provided on the left side of the image display unit 24, and a game ball passes through the through gate 29, so that a normal symbol lottery is performed in the gaming machine 1. Below the image display unit 24, a starting port 26, an electric tulip 27, and a special winning port 28 are provided. The starting opening 26 and the electric tulip 27 are winning openings for paying out a predetermined number of winning balls when a gaming ball enters, and also a winning opening where a jackpot lottery is performed in the gaming machine 1. That is, the start port 26 and the electric tulip 27 are winning ports that are conditions for performing a big win lottery in the gaming machine 1. The electric tulip 27 is provided with a blade member that opens and closes to the left and right, and the blade member is normally closed. Then, when winning the normal symbol lottery performed in association with the passing of the game ball through the through gate 29, the left and right blade members are released for a predetermined time and a predetermined number of times according to the game state, and the game ball is placed on the electric tulip 27. It becomes easy to enter the ball. The big winning opening 28 is a winning opening that opens and closes a predetermined number of times according to the type of winning in the case of winning in the big win lottery. When a game ball enters the big prize opening 28 while the big prize opening 28 is open, the prize balls are paid out in accordance with the number of balls entered. Further, at the bottom of the game area 21, an out port 21a is provided for discharging game balls that have not entered any of the winning ports to the back side of the game board 20.

  A display 30 made up of, for example, a plurality of LED light emitting elements is provided outside the game area 21 and in the lower right part of the game board 20. The display 30 includes, for example, a normal symbol display 31 for displaying a normal symbol lottery result, a normal symbol hold indicator 32 for displaying the number of normal symbol lotteries held, and a special symbol corresponding to the result of the jackpot lottery. It has a special symbol display 33 for displaying, and a special symbol hold indicator 34 for displaying the number of lottery lotteries held. That is, the display 30 is for displaying the result of the normal symbol lottery and the result of the jackpot lottery as the game progresses. Such a display device 30 has a display size smaller than that of the image display device 25 and is displayed in a manner that makes it difficult for the player to grasp the various lottery results. Therefore, the player usually plays a game while visually recognizing the effect image displayed on the image display 25.

  For example, when a game ball launched into the game area 21 enters the start port 26 or the electric tulip 27, the gaming machine 1 performs a big hit lottery as described above. Then, the gaming machine 1 activates the special symbol display 33 to display the special symbol variation for a predetermined time, stops the variation display after the predetermined time has elapsed, and displays the special symbol corresponding to the result of the big hit lottery. As the types of winning in the jackpot lottery, for example, there are “big jackpot” and “small jackpot”. When the jackpot is won, the special symbol display 33 starts a special symbol variation display for a predetermined time. After a lapse, the player stops with a special symbol corresponding to the jackpot displayed. In addition, when winning a small hit, the special symbol display 33 stops after displaying a special symbol corresponding to the small hit after a predetermined time has elapsed since the start of the special symbol variation display. However, the special symbol corresponding to each of the big hit and the small hit is a symbol (display mode) that is difficult to distinguish and grasp at a glance.

  On the other hand, in the image display 25, during the special symbol variation display in the special symbol display 33, for example, three columns of decorative symbols with numbers are displayed. During the variation display of the decorative symbols, various effects such as a notice effect and a reach effect may be performed on the gaming machine 1. For example, when stopping in a state where two rows of decorative symbols out of three rows of decorative symbols are aligned, a shift is made to reach production, and a moving image for reach production is displayed on the image display 25. Further, when a player holds his hand near the surface of the transparent plate unit 4 on the front side of the game board 20 or moves his hand at a predetermined presentation timing during the decorative display variation display or the reach presentation, the hand is moved. The position and moving direction of the player are detected by the distance sensors 9a and 9b, and the image display 25 may produce an effect according to the position of the player's hand and the moving direction of the hand. The three-column decorative symbol variation display is stopped simultaneously with or just before the special symbol variation display on the special symbol display 33 is stopped, and the player is notified of the result of the big hit lottery. For example, if the jackpot is won, the three rows of decorative symbols stop in a state where all the symbols such as “7, 7, 7” are aligned, so that the player can grasp that the jackpot has been won. .

  When the jackpot lottery is won, the gaming machine 1 shifts to the jackpot game (special game state), and the jackpot 28 is opened and closed. In this jackpot game, for example, the opening time per opening for opening the big winning opening 28 is set to a predetermined time (for example, 30 seconds), and the opening setting time for each time elapses or predetermined during the opening. If the number of balls (for example, nine) is counted, a round for closing the special winning opening 28 is repeated a predetermined number of times (for example, 15 rounds). Therefore, the player can acquire a lot of prize balls by putting a lot of game balls into the big prize opening 28 in the jackpot game.

  In addition, when a small win is won in the big win lottery, the gaming machine 1 shifts to a small win game, and in this case, the big winning opening 28 is opened and closed. However, in the small hit game, the opening time per time for opening the big winning opening 28 is set to a shorter time (for example, 0.1 second) than the big hit game. Therefore, in the small hit game, the big winning opening 28 is closed when a predetermined number of balls (for example, nine) are counted as in the case of the big hit game. It is difficult to enter such a large number of game balls into the big winning opening 28 opened to the player, and it is difficult for the player to acquire a lot of prize balls.

  The game board 20 as described above can be visually recognized by the player through the transparent plate unit 4 fitted in the window part 5 of the front frame member 3 during the game. 21 can be visually recognized.

  FIG. 12 is a view of the gaming machine 1 according to the present embodiment as viewed from the front. In the state shown in FIG. 12, the player plays the game while paying attention to the behavior of the game ball launched into the game area 21 through the window portion 5 of the front frame member 3, the display of the decorative symbols on the image display 25, and the like. Do.

  As shown in FIG. 12, the pair of distance sensors 9 a and 9 b attached to the left and right symmetrical positions so as to face the surface side of the transparent plate unit 4 at the upper part of the front frame member 3 are respectively connected from the upper part of the front frame member 3. Ultrasonic waves are transmitted within a range of the predetermined angle θ, and ultrasonic waves are transmitted to almost the entire surface of the game board 20 (particularly, almost the entire game area 21). When there is no player's hand in the vicinity of the surface of the transparent plate unit 4, the ultrasonic waves sent from the distance sensors 9 a and 9 b are sent to the ball receiver 6 and other windows provided at the lower part of the front frame member 3. The light is reflected at the peripheral edge of the portion 5 and the reflected waves are incident on the distance sensors 9a and 9b. That is, in the state where there is no object such as a player's hand near the surface of the transparent plate unit 4, the reflected waves received by the distance sensors 9a and 9b are always in a constant state (steady state).

  On the other hand, when an object such as a player's hand is present near the surface of the transparent plate unit 4, the reflected waves received by the distance sensors 9a and 9b include the reflected waves reflected by the object. It becomes a state different from the steady state. Therefore, the gaming machine 1 extracts a reflected wave different from the steady state from the reflected waves received by the distance sensors 9a and 9b as a reflected wave from an object existing in the vicinity of the surface of the transparent plate unit 4, and each distance. The distance to the object located in the vicinity of the surface of the transparent plate unit 4 is measured by the time difference between the timing at which the sensors 9a and 9b send the ultrasonic wave and the timing at which the reflected wave from the object is received. Here, since each distance sensor 9a, 9b individually measures the distance to an object located near the surface of the transparent plate unit 4, first distance information L1 is obtained from the distance sensor 9a, and from the distance sensor 9b. The second distance information L2 is obtained. And it is present in the vicinity of the surface of the transparent plate unit 4 by performing calculation based on the position information where the distance sensors 9a and 9b are installed and the first and second distance information L1 and L2 obtained by the measurement. It is configured to detect a two-dimensional position (coordinate position on the game board surface) of the object to be played.

  Then, the gaming machine 1 provides the position information of the object (player's hand) on the gaming board surface detected as described above in accordance with the position and moving direction of the player's hand on the gaming board surface. It is used as information for determining whether or not fraudulent acts with a magnet are being performed.

  For example, when the position information is used for effect control, the gaming machine 1 displays the effect image on the image display 25 based on the position information of the object detected as described above (that is, the position information of the player's hand). The contents of the production are controlled to be changed to different contents, such as changing the position, operating the movable accessory, or lighting the lamp. In addition, each distance sensor 9a, 9b repeats the measurement operation at a relatively short period, so that even when an object located near the surface of the transparent plate unit 4 moves on the game board surface, the movement is detected almost in real time. It is also possible. Therefore, the gaming machine 1 can change the content of the presentation to a different content according to the moving direction of the player's hand on the game board surface.

  By the way, in the gaming machine 1 of the present embodiment, when a game ball launched into the game area 21 enters the start opening 26 or the electric tulip 27, the award ball is paid out as described above, and on condition that One big win lottery. Therefore, for example, a player who performs an illegal act that illegally guides a game ball using a magnet tries to increase the number of prize balls to be acquired or to increase the chance of winning a lottery, so that the start opening 26 and the electric motor An operation of bringing the magnet close to the tulip 27 is performed.

  In addition, during the big hit game or the small hit game when the big win lottery is won, the big winning opening 28 is opened. In the big hit game or the small hit game, as described above, when a predetermined number of game balls enter the open big winning opening 28, the big winning opening 28 is closed. However, if the predetermined number of balls is counted and the special winning opening 28 is entered before the predetermined number of balls is counted, the winning balls are paid out even for the portion exceeding the predetermined number of balls. Therefore, a player who performs an illegal act using the magnet performs an operation of bringing the magnet closer to the big winning opening 28 in order to increase the number of winning balls to be acquired during the big hit game or the small hit game.

  Therefore, in the present embodiment, as indicated by a broken line in FIG. 12, the region R1 including the start port 26, the electric tulip 27, and the big winning port 28 on the game board surface is set as the fraud detection region, and the measurement results of the distance sensors 9a and 9b. If an object is detected in the vicinity of the surface of the transparent plate unit 4 based on the above, the player may be cheating on the condition that the object is located in the fraud detection area R1. Is detected. In FIG. 12, a relatively small area including at least the start opening 26, the electric tulip 27, and the big prize winning opening 28 is set as the fraud detection area R1, but the area set as the fraud detection area R1 is the one shown in the figure. It is not limited to. For example, it may be set so as to include a normal winning opening or the like, or almost the entire game area 21 may be set as the fraud detection area R1.

  On the other hand, the coil 8 wound along the peripheral edge portion of the window portion 5 of the front frame member 3 is arranged as shown by a broken line in FIG. The coil 8 accommodates almost the entire game area 21 in which the game ball rolls inside, so that the player can bring the magnet close to the transparent plate unit 4 in any area on the game board surface. Then, the magnetic flux penetrating the coil 8 changes accordingly. As a result, an induced electromotive force is generated in the coil 8 in a direction to cancel the magnetic flux change. Then, the gaming machine 1 detects that an illegal act using a magnet by the player may be performed on condition that the induced electromotive force generated in the coil 8 is detected.

  The gaming machine 1 according to the present embodiment detects a change in magnetism near the surface of the transparent plate unit 4 based on the induced electromotive force generated in the coil 8, and the measurement results of the distance sensors 9a and 9b. A fraudulent act is detected on the condition that an object (such as a player's hand) detected based on the position is located in the fraud detection area R1 on the game board surface. That is, a state in which a change in magnetism is detected in the vicinity of the surface of the transparent plate unit 4 and an object existing in the vicinity of the surface of the transparent plate unit 4 is located in the fraud detection region R1 is a state in which an improper act by a magnet is This is a state that is highly likely to be performed, and the gaming machine 1 detects this state as an unauthorized operation detection state. As described above, the gaming machine 1 according to the present embodiment detects fraud by a magnet based on both the induced electromotive force generated by the coil 8 and the position of the object detected based on the measurement results of the distance sensors 9a and 9b. Therefore, it becomes possible to stably detect fraudulent acts caused by magnets and to reduce false detections.

  However, even when it is determined that the gaming machine 1 is in the unauthorized operation detection state, the operation performed by the player may not actually be an unauthorized act. Therefore, when the gaming machine 1 of the present embodiment is in an unauthorized operation detection state, by detecting a further condition according to the gaming state, it is detected that an illegal act by a magnet is performed, Further, it is configured to enable stable fraud detection and further reduce false detection.

  For example, when the gaming machine 1 is in a big hit game or a small hit game, the big prize opening 28 opens and closes, so a player who performs an illegal act using a magnet brings the magnet close to the big prize opening 28, An operation is performed in which many game balls are illegally guided to the special winning opening 28. Therefore, during the big hit game or the small hit game, the coil 8 generates an induced electromotive force, and the distance sensors 9a and 9b move the object inside the fraud detection region R1 in the vicinity of the transparent plate unit 4. In the detected illegal operation detection state, it is detected that an illegal act using a magnet is performed on condition that the number of winning prizes to the big winning opening 28 within a predetermined time is equal to or more than a predetermined number.

  In addition, when the gaming machine 1 is in a normal gaming state that is not a big hit game or a small hit game, a player who performs an illegal act using a magnet tries to increase the chance of a big hit lottery to the start opening 26 or the electric tulip 27. Repeatedly move the magnet closer. Therefore, in the normal gaming state, the coil 8 generates an induced electromotive force, and the distance sensor 9a, 9b detects an object inside the fraud detection region R1 in the vicinity of the transparent plate unit 4. It is detected that an illegal act by a magnet is performed on condition that the motion detection state is detected a predetermined number of times or more within a predetermined time.

  As described above, the gaming machine 1 of the present embodiment detects a change in magnetism in the vicinity of the surface of the transparent plate unit 4 based on the induced electromotive force generated in the coil 8, and the distance sensors 9a and 9b. When the two conditions that an object (such as a player's hand) detected based on the measurement result is located in the fraud detection area R1 on the game board surface are satisfied, the player is cheating. It is determined that there is a possible illegal operation detection state, and in the illegal operation detection state, another condition according to the gaming state is further determined to detect that an illegal act by a magnet is being performed. Therefore, in this gaming machine 1, false detection of fraudulent acts by magnets is further reduced, and highly reliable fraud detection is possible.

  When a fraudulent act by the magnet is detected, the gaming machine 1 warns the player, informs a nearby store clerk of the fraudulent act, and cheats the hall side computer. A command for notifying that the image is generated is generated and external output is performed. Hereinafter, such a gaming machine 1 will be described in more detail.

  Next, FIG. 13 is a block diagram showing a control mechanism of the gaming machine 1, and shows various control boards attached mainly to the back side of the gaming machine 1 (the back side of the game board 20 in the main body frame 2). The gaming machine 1 includes a main control board 100 that controls main operations related to games, and a sub-control board 200 that controls each unit based on signals and commands output from the main control board 100. In the case of this embodiment, the sub control board 200 includes a payout control board 120, an effect control board 130, an image control board 140, a lamp control board 150, and the like. As described above, the transparent plate unit 4 is provided with the sensor control board 300 for controlling the distance sensors 9a and 9b and the coil 8, and this sensor control board 300 is connected to the main control board 100. Yes.

  The main control board 100 includes a game control unit 50 that controls main operations related to the progress of the game. The main control board 100 also has a start port switch 81 for detecting that a game ball has entered the start port 26 or the electric tulip 27, an electric chew solenoid 82 for opening and closing the electric tulip 27, and the game ball passing through the through gate 29. A gate switch 83 for detecting that the game ball has entered the normal prize opening, a normal prize opening switch 84 for detecting that the game ball has entered the normal prize opening, and a big prize opening switch 85 for detecting that the game ball has entered the big prize opening 28, A big prize opening solenoid 86 that opens and closes the big prize opening 28, a normal symbol display 31, a normal symbol hold display 32, a special symbol display 33, and a special symbol hold display 34 are connected.

  The game control unit 50 includes a CPU 101, a ROM 102, and a RAM 103. When each of the start opening switch 81, the normal winning opening switch 84, and the big winning opening switch 85 detects the entry of a game ball, the game control unit 50 receives a winning ball on the payout control board 120 according to the number of the entering balls. Send a command. The payout control board 120 includes a CPU 121, a ROM 122, and a RAM 123, and is configured to control a payout motor 124 provided on the back side of the game board 20. When a prize ball command is input from the main control board 100, A predetermined number of balls are paid out in accordance with the winning entrance.

  In addition, the game control unit 50 is configured to perform a big hit lottery or a normal symbol lottery. For example, when the gate switch 83 detects the passage of a game ball, a normal symbol lottery for opening and closing the electric tulip 27 is performed, and if elected, the electric chew solenoid 82 is driven for a predetermined time or a predetermined number of times to open the electric tulip 27. . When the start switch 81 detects entry, the game control unit 50 performs a lottery lottery, starts a special symbol variation display on the special symbol display 33, and performs an effect according to the lottery result. In order to do so, a signal or command is sent to the effect control board 130. Also, when the start port switch 81 detects a ball entry, if the special symbol variation display is in progress, the special symbol variation display accompanying the ball entry is suspended and the number of suspensions is displayed on the special symbol hold indicator 34. . In addition, when the big win or the small win is won by the big win lottery by the game control unit 50, the game control unit 50 displays a special symbol corresponding to the hit type after displaying the variation of the special symbol, and opens / closes the big winning opening solenoid 86. The game machine 1 is shifted to the big hit gaming state or the small hit gaming state by controlling each part of the sub-control board 200 according to the hit type.

  In addition, the game control unit 50 receives the first and second distance information L1 and L2 as the measurement results of the distance sensors 9a and 9b from the sensor control board 300, and is detected based on the induced electromotive force of the coil 8. The magnetic detection signal SG2 is input. When the game control unit 50 receives the distance information L1 and L2 and the magnetic detection signal SG2, the game control unit 50 executes a fraud detection process based on them. At this time, the game control unit 50 detects the position information SG1 of the object located near the surface of the transparent plate unit 4 based on the first and second distance information L1, L2, and the player is not cheating. If it is determined, the position information SG1 is output to the effect control board 130. Such fraud detection processing will be described later.

  The effect control board 130 includes a CPU 131, a ROM 132, a RAM 133, and a real-time clock (RTC) 134, and is an effect control means for controlling the execution of various effects as the game progresses. The production control board 130 determines specific production contents based on signals and commands from the main control board 100 and controls each of the image control board 140 and the lamp control board 150. For example, an effect pattern such as a decorative pattern variation display pattern or lighting patterns of various lamps is determined based on a variation pattern input from the main control board 100, and the time during which the special control variation display is performed by the main control board 100 is determined. In the meantime, each of the image control board 140 and the lamp control board 150 is controlled to produce an effect according to the result of the big hit lottery.

  Further, the effect control board 130 receives the position information SG1 of the object detected on the main control board 100 based on the measurement results of the distance sensors 9a and 9b. When the effect control board 130 receives the position information SG1 of the object from the sensor control board 300, the effect contents may be changed accordingly, which will be described later.

  Furthermore, when it is detected that an illegal act using a magnet is performed on the main control board 100, the effect control board 130 is based on an instruction from the main control board 100 and the image control board 140 and the lamp control board 150. Is configured to perform a warning process for the player and a notification process for the surrounding clerk.

  The image control board 140 includes a CPU 141, a ROM 142, a RAM 143, and a VRAM 144. The image control board 140 displays a variation of the decorative symbols on the image display 25 based on an instruction from the effect control board 130 and is designated by the effect control board 130. The display image on the image display unit 25 is controlled, for example, by stopping the variable display with the selected pattern. The image control board 140 performs various effects such as a reach effect and a character appearing on the image display 25 based on the designation from the effect control board 130. The VRAM 144 is a memory that writes an image to be displayed on the image display 25. The CPU 141 executes various processes such as a background image display process, a decorative symbol display process, and a character image display process on the VRAM 144, so that a background image, a decorative symbol image, a character image, etc. are displayed on the image display unit 25. It can be displayed in a superimposed manner. Further, the image control board 140 generates a sound effect or sound for production from the speaker 10.

  Further, the image control board 140 is a warning image for warning the player based on an instruction from the effect control board 130 when it is detected that an illegal act using a magnet is performed by the player. Are displayed on the front side of the various effect images, and a warning sound or the like is output from the speaker 10.

  The lamp control board 150 includes a CPU 151, a ROM 152, and a RAM 153, and various lamps including a frame lamp 11 (including the upper lamp 12 and the lower lamp 13) and a panel lamp 87 based on instructions from the effect control board 130. Is turned on, and the accessory driving unit 88 for driving various movable accessories for production is controlled. Although not shown, the lamp control board 150 is also configured to control a drive mechanism that swings the upper lamp 12 and the lower lamp 13.

  In addition, the lamp control board 150 is a frame lamp for informing a surrounding clerk or the like based on an instruction from the effect control board 130 when it is detected that an illegal act using a magnet is performed by a player. It is also configured to light 11, 12, 13, etc. with a predetermined lighting pattern.

  FIG. 14 is a block diagram illustrating a detailed configuration example of the sensor control board 300. As shown in FIG. 14, the sensor control board 300 includes a timing generation circuit 60 that generates timing signals for driving the distance sensors 9a and 9b, a first distance sensor control unit 61 that controls the distance sensor 9a, and a distance sensor. A second distance sensor control unit 62 that controls 9b, a magnetic detection circuit 64 that detects a change in magnetism in the vicinity of the surface of the transparent plate unit 4 based on the induced electromotive force generated in the coil 8, and the disconnection of the coil 8 A coil diagnosis circuit 65 for diagnosing the presence or absence. Each of these portions is provided inside an overhang portion 43 b formed on the upper portion of the holding portion 43 in the transparent plate unit 4.

  Here, first, details of the control for the distance sensors 9a and 9b will be described. FIG. 15 is a block diagram showing detailed circuit configurations of the first distance sensor control unit 61 and the second distance sensor control unit 62. The timing generation circuit 60 generates a timing signal having a predetermined frequency (for example, 40 kHz), and alternately outputs the timing signal for each of the first distance sensor control unit 61 and the second distance sensor control unit 62 at regular intervals. To do. The first distance sensor control unit 61 and the second distance sensor control unit 62 individually drive the distance sensors 9a and 9b based on the timing signal input from the timing generation circuit 60, and exist in the vicinity of the surface of the transparent plate unit 4. Measure the distance to the object.

  The first distance sensor control unit 61 includes a drive circuit 161, a signal processing circuit 162, a time measurement circuit 163, a distance calculation unit 164, a self-diagnosis circuit 165, and an abnormal output unit 166. Since the second distance sensor control unit 62 has the same configuration as this, the first distance sensor control unit 61 will be described below as an example.

  The drive circuit 161 is a circuit that drives the ultrasonic transmitter 15 included in the distance sensor 9 a based on the timing signal input from the timing generation circuit 60. For example, the drive circuit 161 amplifies an input timing signal and outputs the amplified timing signal to the ultrasonic transmitter 15 so that the ultrasonic transmitter 15 transmits an ultrasonic wave having a predetermined frequency.

  The signal processing circuit 162 is a circuit that processes a pulse signal generated when the ultrasonic receivers 16 and 17 receive ultrasonic waves. The signal processing circuit 162 includes, for example, a filter that extracts only a pulse signal having a predetermined frequency (for example, 40 kHz), a rectifier, an amplifier, and an adder that adds signals output from the ultrasonic receivers 16 and 17. Only the signal component corresponding to the ultrasonic wave transmitted by the ultrasonic transmitter 15 is extracted and transmitted to the time measuring circuit 163 and the self-diagnosis circuit 165.

  The time measuring circuit 163 is a circuit that measures the time required from when the ultrasonic transmitter 15 transmits ultrasonic waves until the ultrasonic receivers 16 and 17 receive reflected waves from the object. A timing signal output from the timing generation circuit 60 is input to the time measurement circuit 163. The time measurement circuit 163 starts time measurement based on the timing signal. Then, from the signal corresponding to the received wave output from the signal processing circuit 162, only the signal component corresponding to the reflected wave from the object located near the surface of the transparent plate unit 4 is extracted, and the ultrasonic receivers 16 and 17 Measure the time required to receive the reflected wave from the object. The time measured by the time measurement circuit 163 is output to the distance calculation unit 164. If the signal component corresponding to the reflected wave from the object located near the surface of the transparent plate unit 4 cannot be extracted within a predetermined time after the time measurement is started, the time measurement operation is stopped. The time is not output to the distance calculation unit 164.

  The distance calculation unit 164 is a processing unit that calculates the distance to an object existing near the surface of the transparent plate unit 4 based on the time input from the time measurement circuit 163. Since the propagation speed of the ultrasonic wave is known, the distance calculation unit 164 calculates the distance to the object by performing a calculation based on the time input from the time measurement circuit 163 and the propagation speed of the ultrasonic wave. Then, the first distance information L1 calculated by the distance calculation unit 164 is output to the main control board 100.

  On the other hand, the self-diagnosis circuit 165 diagnoses whether or not a reflected wave (including a steady-state reflected wave) of the ultrasonic wave is received within a predetermined time after the ultrasonic transmitter 15 transmits the ultrasonic wave. Thus, it is a processing unit that diagnoses whether or not the distance sensor 9a is functioning normally. For example, when a malicious player blocks one or both of the ultrasonic transmitter 15 and the ultrasonic receivers 16 and 17 with any member, the distance measuring function by the distance sensor 9a is stopped. Therefore, the self-diagnosis circuit 165 can detect such an illegal act by always or periodically diagnosing whether or not the distance sensor 9a is functioning normally. Further, the self-diagnosis circuit 165 can detect not only the function stop due to an illegal act but also the case where the distance sensor 9a stops functioning due to a failure or the like. When the self-diagnosis circuit 165 detects that the distance sensor 9a has stopped functioning, it outputs an abnormality signal to the abnormality output unit 166.

  The abnormality output unit 166 is a processing unit that notifies the game control unit 50 of the main control board 100 when the self-diagnosis circuit 165 detects that the distance sensor 9a has stopped functioning. Apart from the detection signal SG2, an abnormal signal indicating that the function of the distance sensor 9a has stopped is output to the game control unit 50.

  The second distance sensor control unit 62 is similar to the above, and the second distance information L2 indicating the distance to the object measured by the distance sensor 9b transmitting and receiving ultrasonic waves from the second distance sensor control unit 62. Is output and provided to the main control board 100.

  When the game control unit 50 of the main control board 100 receives the first and second distance information L1 and L2 from the first and second distance sensor control units 61 and 62, respectively, based on the distance information L1 and L2. By calculating, it is detected what position on the game board surface the object existing in the vicinity of the surface of the transparent plate unit 4 is, and the position information SG1 is output to the effect control board 130 as necessary. This position information SG1 is expressed as, for example, two-dimensional coordinates on the game board surface.

  Here, the concept of processing for detecting the position of an object in the game control unit 50 of the main control board 100 will be described. FIG. 16 is a front view of the gaming machine 1 and detects the position of the object M based on the first distance information L1 measured by the distance sensor 9a and the second distance information L2 measured by the distance sensor 9b. The concept of processing is shown. As shown in FIG. 16, when the distance from the distance sensor 9a to the object M is L1, the object M is located at some position on the arcuate line La having the radius L1 with the position of the distance sensor 9a as the center. Exists. On the other hand, if the distance from the distance sensor 9b to the object M is L2, the object M exists at some position on the arc-shaped line Lb having the radius L2 with the position of the distance sensor 9b as the center. Therefore, the object M in the vicinity of the surface of the transparent plate unit 4 is located on the intersection of the two lines La and Lb. Therefore, the game control unit 50 performs calculations based on the installation positions of the distance sensors 9a and 9b on the game board surface, the first distance information L1, and the second distance information L2, and the two lines La and Lb. The position of the object M is detected by obtaining the intersection point.

  By the way, when the intersection of two lines La and Lb is calculated | required as mentioned above, two intersections may be calculated | required. In this case, if one intersection is located outside the transparent plate unit 4, the other intersection (that is, the intersection located inside the transparent plate unit 4) can be specified as the position where the object M exists. . However, each of the two intersections may be located inside the transparent plate unit 4. FIG. 17 shows such a case. The arc-shaped line La having a radius L1 centered on the position of the distance sensor 9a and the arc-shaped line Lb having a radius L2 centered on the position of the distance sensor 9b are shown. The intersection is located inside the transparent plate unit 4. In such a case, of the two positions of the object M1 and the object M2 shown in FIG. 17, the position where the object actually exists cannot be accurately specified, but the game control unit 50 does not detect the object M1 and the object M2. One of the two positions is selected to identify the position of the object M. For example, the position closer to the center of the transparent plate unit 4 is selected from the two positions of the object M1 and the object M2, and the position of the object M is detected.

  In the present embodiment, the distance sensors 9a and 9b are provided at two positions above the transparent plate unit 4, whereas the fraud detection region R1 is set at the lower center of the transparent plate unit 4 (see FIG. 12), the two intersections of the lines La and Lb are both inside the transparent plate unit 4 and any one of them is located in the fraud detection region R1. Therefore, as described above, even if the game control unit 50 appropriately selects one of the two positions of the object M1 and the object M2, the object actually located in the fraud detection region R1 In contrast, an object that is not actually located in the fraud detection region R1 is not erroneously detected as an object that is located in the fraud detection region R1.

  When the position of the object M is detected as described above, the game control unit 50 next determines whether or not the object M is located in the fraud detection region R1, thereby performing an illegal act using a magnet. Determine whether or not there is a possibility. When the position of the object M is included in the fraud detection region R1, processing for determining further conditions for determining fraud is performed. On the other hand, when the position of the object M is not included in the fraud detection region R1, the detected position information SG1 is output to the effect control board 130.

  Next, details of processing for detecting a change in magnetism based on control on the coil 8 and induced electromotive force generated in the coil 8 will be described. FIG. 18 is a diagram illustrating a concept of signal processing in the magnetic detection circuit 64 when an illegal act using a magnet is performed. When moving the magnet M from the front side of the gaming machine 1 in the direction F1 approaching the transparent plate unit 4 and moving the magnet M in the direction F2 away from the transparent plate unit 4 as shown in FIG. The magnetic flux passing through the coil 8 provided in the front frame member 3 increases, for example, at first, and then decreases. Therefore, the coil 8 outputs the output signal (induced electromotive force V) shown in FIG. 18B as the magnet M moves in the directions F1 and F2. When the winding direction of the coil 8 is the reverse direction, the sign of the induced electromotive force V is opposite to that shown in FIG.

  The magnetic detection circuit 64 includes various circuits such as a signal amplifier, a noise removal circuit, an inverting circuit, and an A / D converter, for example, and an induced electromotive force V output from the coil 8 as shown in FIG. On the other hand, the magnetic detection signal SG2 is output by sequentially performing signal processing in these various circuits. The magnetic detection signal SG2 is a signal corresponding to the induced electromotive force V generated by the coil 8, and is output as a digital signal, for example. Then, by appropriately setting the number of turns of the coil 8 and various circuit parameters in the magnetic detection circuit 64, a magnet having a magnetic force capable of attracting the game ball via the transparent plate unit 4 becomes a transparent plate unit 4. , The magnetic detection signal SG2 corresponding to that can be output.

  In particular, since the coil 8 is wound around the front frame member 3 so as to surround the game area 21, the magnet M moves in the direction F1 in which the magnet M approaches the transparent plate unit 4 as shown in FIG. In the case of moving in the away direction F2, a relatively large induced electromotive force is generated in the coil 8. Therefore, it is possible to satisfactorily detect an initial operation of the player who tries to bring the magnet M close to the transparent plate unit 4 in order to perform an illegal act.

  Further, if the magnet is moved in the vertical and horizontal directions with respect to the game area 21 while the magnet is in close proximity to the transparent plate unit 4, the magnetic flux penetrating the coil 8 also changes to some extent. Therefore, also in this case, an induced electromotive force is generated in the coil 8. The induced electromotive force generated at this time is a small electromotive force as compared with the case of moving in the direction F1 or F2 shown in FIG. 18A, but the signal amplification factor in the magnetic detection circuit 64 is set to an appropriate value in advance. It is possible to satisfactorily detect the magnetic change accompanying the movement of the magnet by adjusting to the above.

  As described above, the gaming machine 1 according to the present embodiment can detect a change in magnetism caused by the coil 8 and the magnetism detection circuit 64 if the magnet moves in the vicinity of the game area 21. In particular, it has high sensitivity to the movement of the magnet approaching the game area 21 and the movement of the magnet moving away from the game area 21.

  When the magnetic detection circuit 64 detects a change in magnetism based on the induced electromotive force V generated in the coil 8 as described above, the magnetic detection signal SG2 generated thereby is generated as shown in FIG. It is output to 100 game control units 50.

  Next, FIG. 19 is a diagram illustrating a configuration example of the coil diagnosis circuit 65. The coil diagnostic circuit 65 is interposed between the coil 8 and the magnetic detection circuit 64, for example. As shown in FIG. 19, the coil diagnosis circuit 65 includes a current source 65a connected to one end of the coil 8, a current detector 65b connected to the other end of the coil 8, and a detection result of the current detector 65b. And an abnormality detection unit 65c that detects the disconnection of the coil 8, and when the abnormality detection unit 65c detects the disconnection of the coil 8, an abnormality signal is output to the main control board 100. ing.

  The current source 65 a generates a weak constant current and causes the constant current to flow to one end of the coil 8. When the coil 8 is not disconnected, the current detector 65b detects a constant current generated by the current source 65a. On the other hand, when the coil 8 is disconnected, the current detector 65b does not detect a constant current generated by the current source 65a. The abnormality detection unit 65c determines the disconnection of the coil 8 based on the current value detected by the current detection unit 65b. For example, when the current detection unit 65 b does not detect any current, the abnormality detection unit 65 c determines that the coil 8 is disconnected and outputs an abnormality signal to the main control board 100. If the current detection unit 65b detects a current, the abnormality detection unit 65c determines that the coil 8 is not disconnected, and does not output an abnormality signal to the main control board 100. By providing such a coil diagnosis circuit 65, it is possible to self-diagnose whether the coil 8 is functioning normally. The coil diagnosis circuit 65 may always perform self-diagnosis after powering on the gaming machine 1 or may perform self-diagnosis repeatedly at regular time intervals after power-on. good.

  As described above, the sensor control board 300 provided in the transparent plate unit 4 outputs the first distance information L1, the second distance information L2, and the magnetic detection signal SG2 to the game control unit 50 of the main control board 100. To do. Note that power is supplied to the sensor control board 300 through the cable 19 described above.

  By the way, the game control unit 50 shown in FIG. 13 performs control according to the progress of the game by outputting signals and commands to the sub-control board 200 as described above. In particular, the first distance information L2, the second distance information L2, and the magnetic detection signal SG2 output from the sensor control board 300 are monitored. And the game control part 50 determines whether it is an unauthorized operation detection state based on these distance information L1, L2 and the magnetic detection signal SG2. That is, the game control unit 50 receives the magnetic detection signal SG2 indicating that a change in magnetism near the surface of the transparent plate unit 4 is detected, and the distance information L1 input from the sensor control board 300 When the object detected based on L2 is located inside the predetermined fraud detection area R1, it is determined that the player is in an illegal operation detection state where there is a high possibility that an illegal act by the player is being performed.

  FIG. 20 is a diagram illustrating the position of the object M in the case where the game control unit 50 determines that the state is an unauthorized operation detection state. When the magnetic detection signal SG2 is input to the game control unit 50, as shown in FIG. 20, when the position of the object M detected by the game control unit 50 is included in the fraud detection area R1, game control is performed. The unit 50 determines that the operation performed by the player is an unauthorized operation detection state in which there is a high possibility that the operation is an unauthorized act.

  On the other hand, when the game control unit 50 detects that an object existing near the surface of the transparent plate unit 4 is in a region other than the fraud detection region R1, the game control unit 50 does not determine that the state is an unauthorized operation detection state. That is, as shown in FIG. 21, when the position of the object M detected by the game control unit 50 is in a region other than the fraud detection region R1, regardless of whether or not the magnetic detection signal SG2 is input, The game control unit 50 determines that the act by the player is not an illegal act.

  In addition, even if the game control unit 50 receives the magnetic detection signal SG2 from the magnetic detection circuit 64, the game control unit 50 does not detect the illegal operation when the distance information L1 and L2 are not input from the sensor control board 300. Not determined. That is, also in this case, it is determined that the act by the player is not an illegal act.

  When the game control unit 50 determines that the state is an unauthorized operation detection state, the game control unit 50 further determines the game state of the gaming machine 1 and performs an action by the player based on an additional condition determined according to the game state. Determine whether it is a fraud. For example, in the case of a big hit game or a small hit game, the game control unit 50 determines whether or not the number of winnings to the big winning opening 28 within a predetermined time is equal to or more than a predetermined number in the illegal operation detection state. If there are more than a predetermined number of winnings, it is detected that the player is cheating using a magnet. Further, for example, when the gaming machine 1 is in a normal gaming state, the game control unit 50 determines whether or not the unauthorized operation detection state is detected a predetermined number of times within a predetermined time. Detect that a person is cheating using a magnet.

  When the game control unit 50 finally determines that the player is performing an illegal act using a magnet, the game control unit 50 executes various processes for coping with the illegal activity performed by the player at that timing. To do. For example, by outputting a fraud warning command to the effect control board 130, a warning image is superimposed on the front side of the decorative design on the image display 25, or a warning is issued from the speaker 10. Generate sound. Further, the surrounding lamps and the like are informed by lighting the frame lamp 11 and the like in a predetermined pattern. In addition, the game control unit 50 externally outputs a fraud notification command for notifying that a fraudulent act by a magnet is being performed to a hall computer via a communication interface (not shown). Thereby, on the hall side, it is possible to grasp in real time which gaming machine is likely to be cheated by the magnet among a large number of installed gaming machines.

  When the game control unit 50 receives an abnormal signal from the sensor control board 300 as a result of the self-diagnosis of the distance sensors 9a and 9b and the coil 8 being performed on the sensor control board 300, the game control unit 50 determines the distance at that timing. Various processes for dealing with abnormalities of the sensors 9a and 9b and the coil 8 are executed. For example, by outputting an abnormal command to the effect control board 130, an image such as “Please call a clerk” is displayed on the image display unit 25 so as to be superimposed on the front side of the decorative design, or from the speaker 10. The sound of Further, the surrounding lamps and the like are informed by lighting the frame lamp 11 and the like in a predetermined pattern. In addition, the game control unit 50 notifies the hall computer via a communication interface (not shown) that one or both of the two distance sensors 9a and 9b are in an abnormal state, or the coil 8 is in an abnormal state. Generate a command to notify that and output it externally. Thereby, on the hall side, it is possible to grasp in real time which one of the installed gaming machines has the malfunction of the distance sensors 9a, 9b and the coil 8.

  Here, a processing procedure of the above-described operation performed by the game control unit 50 of the main control board 100 will be described. FIG. 22 is a flowchart showing main operations of the game control unit 50. The game control unit 50 repeats the process based on the flowchart shown in FIG. 22 as a timer interrupt process at regular intervals (for example, 4 milliseconds) during normal operation except for special cases such as when the power is turned on or when the power is turned off. Configured to run.

  When the game control unit 50 starts this process, the random number update process (step S101), the start port switch process (step S102), the gate switch process (step S103), the various switch processes (step S104), and the prize ball process (steps) S105), special symbol processing (step S106), normal symbol processing (step S107), special prize opening processing (step S108), electric tulip (electric chew) processing (step S109), fraud detection processing (step S110), abnormal The detection process (step S111) and the output process (step S112) are sequentially executed. When these processes are completed, the initial value random number update process (step S113) is repeatedly executed. Then, when a predetermined time has elapsed and the next interruption by the timer occurs, the process after the random number update process (step S101) is executed again, and this process is repeated thereafter.

  In the random number update process (step S101), a process of updating the values of various random numbers such as jackpot random numbers, symbol random numbers, reach random numbers stored in the random number storage area of the RAM 103 is executed.

  In the start port switch process (step S102), the state of the start port switch 81 is monitored. When the start port switch 81 is turned on, the number of lottery lotteries is checked, and the number of holds is a predetermined number. If it is less, the process of incrementing the hold number is performed, and further, a process of acquiring various random numbers such as a jackpot random number for the jackpot lottery from the random number storage area is performed. The lottery result in the jackpot lottery is determined by the jackpot random number acquired at this time.

  In the gate switch process (step S103), the state of the gate switch 83 is monitored. If the gate switch 83 is on, the number of normal symbol lotteries is confirmed, and the number of retained is less than a predetermined number. If there is, processing for incrementing the number of holdings is performed, and further processing for obtaining a random number for normal symbol lottery is executed. The lottery result in the normal symbol lottery is determined by the random number acquired at this time.

  Then, in various switch processes (step S104), input processes from all other switches (for example, a normal prize opening switch, a big prize opening switch, etc.) are performed, and in the prize ball process (step S105), the number of prizes received in various prize openings. And a prize ball command for outputting to the payout control board 120 is set based on the counted value.

  In the special symbol process (step S106), a special symbol variation display and a process associated with the variation display are performed. For example, when the number of holds in the big hit lottery is 1 or more, the hold is digested and the special symbol variation display is started. At this time, a jackpot lottery (a jackpot determination) is performed based on the reserved jackpot random number. Then, a change pattern for outputting to the effect control board 130, a command for starting a change display of the decorative symbols, and the like are set in order to perform an effect according to the result of the big hit lottery during the special symbol change display.

  In the normal symbol processing (step S107), the normal symbol variation display and the processing associated with the variation display are performed. For example, when the number of holdings of the normal symbol lottery is 1 or more, the holding of the normal symbol is started and the fluctuation display of the normal symbols is started. At this time, a normal symbol lottery is performed based on the reserved random number.

  In the big prize opening process (step S108), after the special symbol change display, the process of opening and closing the big prize opening 28 is performed when the game shifts to the big hit game or the small hit game. By this process, the big hit game or the small hit game when winning in the big hit lottery is performed.

  In the electric tulip process (step S109), when the normal symbol lottery is won in the normal symbol process (step S107), the electric tulip 27 is released.

  Then, in the cheating detection process (step S110), a process of determining whether or not the act by the player is a cheating is performed based on the distance information L1 and L2 output from the sensor control board 300 and the magnetic detection signal SG2. To do. At this time, the game control unit 50 functions as fraud detection means.

  23 to 25 are flowcharts showing an example of a detailed processing procedure of this fraud detection process (step S110). In this process, first, it is determined whether distance information L1, L2 is input from the sensor control board 300 (step S121). If the distance information L1 and L2 are not input (NO in step S121), since the fraud is not performed, the fraud detection flag is set to off (step S122), and this process is terminated. To do.

  On the other hand, when the distance information L1 and L2 are input (YES in step S121), the game control unit 50 detects the position of the object on the game board surface by performing a calculation based on the distance information L1 and L2. (Step S123). Thereby, the position information SG1 of the object is generated. Then, the game control unit 50 determines whether or not an object existing on the game board surface is located in the fraud detection area R1 (step S124). If the position information SG1 of the object is in an area other than the fraud detection area R1 (NO in step S124), the fraudulent act is not performed. Therefore, in this case, the game control unit 50 sets the detected position information SG1 of the object as position information SG1 for outputting to the effect control board 130 (step S125). Then, the fraud detection flag is set to off (step S122), and this process ends.

  On the other hand, if the position information SG1 of the object is in the fraud detection region R1 (YES in step S124), there is a possibility that a fraudulent act using a magnet has been performed. Therefore, the game control unit 50 determines whether or not the magnetic detection signal SG2 is input from the sensor control board 300 (step S126). As a result, if the magnetic detection signal SG2 has not been input (NO in step S126), no fraud has been performed, so the fraud detection flag is set to off (step S122), and this process is performed. finish. On the other hand, when the magnetic detection signal SG2 is input from the sensor control board 300 (YES in step S126), an unauthorized operation detection state is entered, and an unauthorized act detection process corresponding to the gaming state is executed.

  That is, when it is determined that the state is an unauthorized operation detection state (YES in step S126), the game control unit 50 determines whether the current gaming state of the gaming machine 1 is a big hit or a small hit. (Step S127). If it is a big hit or a small hit (YES in step S127), a first fraud detection process is executed (step S128). On the other hand, if it is not a big hit or a small hit (NO in step S127), a second fraud detection process is executed (step S129).

  FIG. 24 is a flowchart illustrating an example of a detailed processing procedure of the first fraud detection process (step S128). In this process, if the number of winning a prize winning opening 28 within a predetermined time is equal to or greater than the predetermined number, it is determined that an illegal act is being performed, and various warning and notification commands are set. First, the game control unit 50 determines whether or not time measurement is being performed (step S131), and when time measurement is not being performed (NO in step S131), time measurement is started (step S132). On the other hand, if time measurement has already started, step S132 is skipped. Then, the game control unit 50 determines whether or not there is a winning at the big winning opening 28 (step S133), and when there is a winning (YES at step S133), the number of winnings is counted up according to the winning number. (Step S134). If there is no winning in the big winning opening 28, step S134 is skipped.

  Then, the game control unit 50 determines whether or not the measurement for a predetermined time has ended after the time measurement is started (step S135). In the first fraud detection process, the predetermined time is set to about several seconds, for example. If the predetermined time has not elapsed (NO in step S135), this process is terminated, and thereafter, the process is repeatedly executed, so that the game ball is further increased to the big winning opening until the predetermined time elapses. When entering 28, the number of winnings is counted up accordingly.

  When the predetermined time has elapsed (YES in step S135), the game control unit 50 determines whether or not the number of winnings is equal to or greater than a predetermined number (step S136), and if it is equal to or greater than the predetermined number (YES in step S136). Then, a fraud warning command for output to the production control board 130 is set (step S137), and then the fraud notification for external output for notifying the hall computer that the fraud is being performed. A command is set (step S138). On the other hand, if the number of winnings is less than the predetermined number (NO in step S136), the process is terminated without setting those commands. The count value of the number of winnings is reset at an appropriate timing when a predetermined time has elapsed (YES in step S135).

  As described above, in the first fraud detection process (step S128), if the number of winnings to the big winning opening 28 becomes equal to or larger than a predetermined number within a predetermined time during the big hit game or the small hit game, the fraud by the magnet It is determined that an action is being performed. When it is determined that an illegal act using a magnet is being performed, various commands for warning and notification are set.

  Next, FIG. 25 is a flowchart illustrating an example of a detailed processing procedure of the second cheating detection process (step S129). In this process, it is determined that an illegal operation is detected by detecting a predetermined number of times within a predetermined time and an illegal action is performed, and various warning and notification commands are set. First, the game control unit 50 determines whether or not time measurement is being performed (step S141), and when time measurement is not being performed (NO in step S141), time measurement is started (step S142). On the other hand, if time measurement has already started, step S142 is skipped. The game control unit 50 determines whether or not the fraud detection flag is off (step S143). If the fraud detection flag is off (YES in step S143), the game control unit 50 turns on the fraud detection flag (step S144). Then, the number of fraud detections is counted up (step S145). If the fraud detection flag is already on (NO in step S143), steps S144 and S145 are skipped.

  Then, the game control unit 50 determines whether or not the count value of the number of fraud detections is a predetermined number or more (step S146). Here, if the count value of the number of fraud detections is equal to or greater than the predetermined number (YES in step S146), a fraud warning command to be output to the production control board 130 is set (step S147), and then the hall side computer is set. On the other hand, a fraud notification command for external output for notifying that a fraudulent act is being performed is set (step S148). On the other hand, if the count value is less than the predetermined number (NO in step S146), those commands are not set.

  Then, the game control unit 50 determines whether or not the measurement of the predetermined time has ended after the time measurement is started (step S149). In the second fraud detection process, the predetermined time is set to about several tens of seconds or about several minutes, for example. If the predetermined time has not elapsed (NO in step S 149), this process ends, and thereafter, this process is repeatedly executed, so that the improper operation is detected until the predetermined time elapses. Is detected a predetermined number of times or more, a command for warning or notification is set at that time. If the predetermined time has elapsed (YES in step S149), the count value of the number of fraud detections is cleared (step S150).

  As described above, in the second cheating detection process (step S129), it is detected a predetermined number of times or more in a normal operation state that is not a big hit game or a small hit game during a predetermined time. Then, it is determined that an illegal act using the magnet is being performed. When it is determined that an illegal act using a magnet is being performed, various commands for warning and notification are set.

  Returning to FIG. 22, in the abnormality detection process (step S <b> 111), a process of confirming whether or not an abnormality signal related to the distance sensors 9 a and 9 b or the coil 8 is output from the sensor control board 300 is performed. FIG. 26 is a flowchart illustrating an example of a detailed processing procedure of the abnormality detection process (step S111). In this process, first, it is determined whether or not an abnormal signal is input from the sensor control board 300 (step S161). If an abnormal signal is input (YES in step S161), an abnormality notification command to be output to the effect control board 130 is set (step S162), and then the distance sensors 9a and 9b are sent to the hall computer. Alternatively, an abnormality notification command for external output for notifying that an abnormality has occurred in the coil 8 is set (step S163). On the other hand, if no abnormal signal is input (NO in step S161), this process ends.

  In the output process (step S112) in FIG. 22, various commands set in the above processes are output to the payout control board 120 or the effect control board 130. In addition, here, the external output commands set in each of the above processes are also externally output to the hall computer via a communication interface (not shown).

  In the initial value random number update process (step S113), using the remaining time until the next timer interrupt occurs, various random numbers such as jackpot random numbers, symbol random numbers, reach random numbers stored in the random number storage area are stored. The process of updating the initial value is repeatedly executed. Since the remaining time until the next timer interrupt is generated varies depending on the state of the gaming machine 1, the initial values of various random numbers updated by repeatedly executing this process are irregular. Therefore, even when trying to generate jackpots illegally using a sensory device that generates a bodily sensation signal at regular intervals, since the initial value of the jackpot random number is unknown, the timing at which the jackpot random number becomes the winning value of the jackpot It cannot be grasped, and such illegal acts can be prevented.

  By performing the processing as described above, the game control unit 50 controls the progress of the game in the gaming machine 1, and during the game, the player magnets the start port 26, the electric tulip 27, or the grand prize winning port 28. When an illegal act is performed, the player is warned and further notified to the surrounding clerk and the hall side. Therefore, according to the gaming machine 1 of the present embodiment, if a fraudulent act by a magnet is performed during the game, the surrounding clerk or the hall side can quickly grasp it, and prompt action against the fraudulent act It becomes possible to do. In the gaming machine 1 of the present embodiment, the distance sensors 9a and 9b for detecting an object located near the surface of the transparent plate unit 4 are the peripheral portions of the transparent plate unit 4 and the two upper portions of the front frame member 3. Since the coil 8 is arranged along the peripheral edge of the transparent plate unit 4, the distance sensors 9 a and 9 b and the coil 8 do not deteriorate the visibility of the game area 21. It is an aspect.

  Next, details of the processing in the effect control board 130 will be described. The effect control board 130 executes various processes based on various commands output from the main control board 100. Here, the position information SG1 of the object detected based on the measurement results of the distance sensors 9a and 9b. That is, 2 of the process of changing the effect content performed during the game based on the position information SG1 input from the main control board 100 and the warning process performed when the cheating warning command is received from the main control board 100 One process will be described.

  First, an example of processing in which the effect control board 130 changes the contents of the effect being performed during the game based on the position information SG1 input from the main control board 100 to a different effect will be described.

  When the effect control board 130 receives the variation pattern from the main control board 100 as described above, the effect control board 130 determines an effect pattern such as a decoration display variation display pattern on the image display 25 based on the variation pattern. Then, when a command for starting the decorative display of the decorative pattern is further input from the main control board 100, the decorative display of the decorative pattern is started to perform an effect corresponding to the determined effect pattern. Here, the effect pattern determined by the effect control board 130 may include a change effect pattern for switching effect contents when the player performs a predetermined operation. In this case, after starting the decorative display variation display, the effect control board 130 determines whether or not the position information SG1 is input from the main control board 100 at a predetermined effect timing defined in the effect pattern being executed. If the position information SG1 is input after confirmation, the effect pattern currently being executed is changed to an effect pattern for switching based on the position information SG1. Hereinafter, the operation in the case where the effect control board 130 switches the effect pattern will be described.

  FIG. 27 is a flowchart illustrating an example of a processing procedure in which the effect control board 130 changes the effect contents based on the measurement results of the distance sensors 9a and 9b. This process is a process that is periodically executed when a predetermined effect is being executed, for example, when a decorative symbol is being displayed on the effect control board 130. When the effect control board 130 starts this process, it determines whether or not the effect is being executed (step S201). If the performance is not being executed, the process is terminated without performing the subsequent processes. On the other hand, if the effect is being executed (YES in step S201), it is determined whether or not the effect pattern for switching is included in the effect pattern currently being executed (step S202). When the effect pattern currently being executed does not include the effect pattern for switching (NO in step S202), the process is terminated without performing the subsequent processes. In this case, it is executed as it is until the currently executed effect is completed. On the other hand, if the effect pattern currently being executed includes an effect pattern for switching (YES in step S202), effect control board 130 detects a predetermined position information SG1 output from main control board 100. It waits until it becomes an effect timing (step S203), and when it becomes the effect timing (YES in step S203), it is determined whether or not the position information SG1 is input from the main control board 100 (step S204).

  At this time, for example, as shown in FIG. 28, the effect control board 130 displays an effect image for causing the player to perform some operation (hand movement) on the image display 25. In the example shown in FIG. 28, the player is prompted to select one effect pattern from among the three effect patterns (effect A, effect B, effect C). In this case, when the player performs an operation of selecting a desired effect pattern toward the image display 25, the player grasps that the effect being executed changes to a different effect pattern. The player then performs such an operation in the hope that the currently executed performance will change to a performance with a higher level of expectation for the jackpot. As a result, since the distance sensors 9a and 9b detect the player's hand, the effect control board 130 inputs the position information SG1 from the main control board 100.

  The effect control board 130 is in an input standby state for the position information SG1 indicating the position of the player's hand until a predetermined time elapses after the effect timing for detecting the position information SG1 is reached (steps S204 and S205). If the position information SG1 has not been input before the predetermined time has elapsed (YES in step S205), the process ends without switching the effect pattern. In this case, it is executed as it is until the effect pattern currently being executed ends.

  On the other hand, when the position information SG1 is input before the predetermined time has elapsed (YES in step S204), the effect control board 130 switches the current effect pattern based on the position information SG1 of the player's hand. Switching to the pattern (step S206). For example, in the state shown in FIG. 28, when the player holds his / her hand on the front side of the image of the effect A, the effect control board 130 switches the effect corresponding to the effect A based on the position information SG1 of the player's hand. The pattern is specified, the effect pattern currently being executed is switched to the effect pattern for switching effect A selected by the player, and the subsequent effect is executed. The same applies when the player holds his hand over the front side of the effect B image or the effect C image. Then, the effect based on the effect pattern for switching selected by the player is performed until the decorative symbol variation display ends.

  As described above, the gaming machine 1 of the present embodiment can detect the position of the player's hand near the surface of the transparent plate unit 4 based on the measurement results of the distance sensors 9a and 9b. Thus, a plurality of options can be displayed on the image display 25 and the player can select them. That is, since one option selected by the player among a plurality of options displayed on the image display 25 can be specified, a variety of effect patterns to be switched at a predetermined effect timing can be set. . Therefore, various effects can be performed by allowing the player to select one effect pattern from among many effect patterns.

  Further, in the flowchart of FIG. 27, the case where the presentation pattern is switched based on the position information SG1 specifying the position of the player's hand is exemplified. You may make it detect the moving direction of a hand and switch an effect pattern according to the moving direction. As an example, if the player performs an operation that cuts the currently displayed decorative symbol by hand at a predetermined performance timing, an image is displayed that cuts the decorative symbol in accordance with the movement of the hand. If the cutting operation is successful within a predetermined time, it is possible to produce an effect such as changing the currently displayed decorative symbol to another decorative symbol. In addition, there are various effects.

  In addition, although the case where the effect performed during the change display of the decoration symbol is switched to another effect based on the position information SG1 is illustrated here, the change of the effect content based on the position information SG1 is not necessarily the change display of the decoration symbol. It is not limited to being inside. For example, the effect during the big hit game or the small hit game may be switched to another effect based on the position of the player's hand.

  Next, an example of warning processing that is performed when the production control board 130 receives a fraud warning command from the main control board 100 will be described.

  The effect control board 130 periodically or constantly monitors whether or not an illegal action warning command is output from the main control board 100 while performing the effect control as described above. Upon receiving the cheating warning command, various commands are output to the image control board 140 and the lamp control board 150 to warn the cheating to the player and to cheat the surrounding clerk. A process for notifying that there is a possibility of being present is executed. Hereinafter, an operation in the case where the effect control board 130 performs a warning process will be described.

  FIG. 29 is a flowchart illustrating an example of a processing procedure regarding warning processing performed by the effect control board 130. This process is, for example, a process that is periodically executed on the effect control board 130. When starting the process, the effect control board 130 determines whether or not an illegal action warning command has been received from the main control board 100 (step S211). If a warning command has not been received, the process is terminated without performing the subsequent processes. On the other hand, if a warning command is received (YES in step S211), a warning image display command is output to the image control board 140 (step S212), and a warning voice output command is further output (step S213). Subsequently, a warning lighting pattern command is output to the lamp control board 150 in order to light the frame lamp 11 and the like with a predetermined warning lighting pattern (step S214).

  FIG. 30 is a diagram illustrating an example of the warning image G1 displayed on the image display 25 by the warning process. As shown in FIG. 30, when the effect control board 130 performs the above-described processing, for example, a warning image G <b> 1 such as “Please release your hand from the glass surface” is displayed on the image display 25. It is displayed on the front side of the fluctuating display and other effect images. At this time, a warning sound is output from the speaker 10, and the frame lamp 11 and the like are lit in a predetermined warning lighting pattern. Therefore, it is possible to stop the cheating by the player who is cheating using the magnet.

  As described above, the gaming machine 1 of this embodiment includes the coil 8 wound along the peripheral edge of the transparent plate unit 4 that can be attached to and detached from the window 5 of the front frame member 3, and the peripheral edge of the transparent plate unit 4. And two distance sensors 9a and 9b provided in the section. The main control board 100 for controlling the progress of the game has a magnetic detection signal SG2 detected based on the induced electromotive force generated in the coil 8, and distance information L1, measured by each of the plurality of distance sensors 9a, 9b. L2 is input, and it is determined whether or not a magnetic change in the vicinity of the window portion 5 is detected based on the magnetic detection signal SG2, and the position of the object on the game board surface based on the distance information L1 and L2. Is detected to determine whether or not the object exists in a predetermined fraud detection area R1 on the game board surface. The main control board 100 detects a change in magnetism in the vicinity of the window portion 5 and performs a fraudulent act using a magnet on the condition that an object existing in the fraud detection area R1 is detected. Detect that. Therefore, the gaming machine 1 of the present embodiment can stably detect fraudulent acts using magnets without reducing the visibility of the gaming area 21, and can reduce false detection of fraudulent acts. is there.

  More specifically, since the coil 8 is provided between the transparent glass plates 41 and 42 in the transparent plate unit 4, the coil 8 is in a protected state, and the coil 8 is intentional. It has a structure that can prevent cutting. In addition, the two distance sensors 9a and 9b are provided in an overhanging portion 43b that protrudes to the front side above the holding portion 43 in the transparent plate unit 4, and the transparent plate unit 4 has a transparent plate unit 4 from above. Since ultrasonic waves can be transmitted and received near the surface, the distance to the object existing near the surface of the transparent plate unit 4 can be favorably performed.

  Further, since the sensor control board 300 for controlling the coil 8 and the distance sensors 9a and 9b is provided in the transparent plate unit 4, the wiring for connecting the coil 8 and the distance sensors 9a and 9b from the sensor control board 300 is short. be able to. Therefore, it is possible to suppress the possibility that these wirings become antennas and be affected by noise, and highly accurate magnetic detection and distance measurement are possible.

(Modification)
As mentioned above, although several embodiment regarding this invention was described, this invention is not limited to the content mentioned above, A various modification is applicable.

  For example, in the above-described embodiment, a gaming machine in which a big hit lottery is performed when a game ball enters the start opening 26 and the big winning opening 28 is opened and closed a predetermined number of times when the big hit lottery is won is exemplified. However, the gaming machine of the present invention is not necessarily limited to such a gaming machine, and various gaming machines other than the above-described gaming machines (for example, gaming machines called “blade mono”, “right mono”, etc.) Of course, the present invention can also be applied to the above.

  Moreover, although the case where one fraud detection area | region R1 was set with respect to the game board 20 was illustrated in embodiment mentioned above, you may set a some fraud detection area | region. Moreover, although the case where an ultrasonic sensor was employ | adopted as an example of distance sensor 9a, 9b was illustrated in embodiment mentioned above, it is not restricted to this, For example, you may employ | adopt the optical sensor which projects and receives invisible light. Further, the number of distance sensors is not limited to two, and three or more distance sensors may be provided.

  In the above-described embodiment, mainly, the coil 8 generates an induced electromotive force, and an object detected based on the measurement results of the distance sensors 9a and 9b is located in the fraud detection region R1. Although the case where it determined that it is an unauthorized operation detection state was illustrated, it is not restricted to this. For example, when the coil 8 generates an induced electromotive force, if an object is detected at an arbitrary position near the surface of the transparent plate unit 4 based on the measurement results of the distance sensors 9a and 9b, an illegal operation is thereby performed. You may determine with it being in a detection state. In this case, since it is not necessary to determine whether or not the position of the object based on the position information SG1 is in the fraud detection region R1 in the game control unit 50, it is possible to perform more efficient fraud determination. Become.

  Further, in the above-described embodiment, as an example of the fraud detection process during the big hit game or the small hit game, the coil 8 generates an induced electromotive force, and the distance sensors 9a and 9b are in the vicinity of the window portion 5. In the illegal operation detection state in which an object is detected, an example has been described in which an illegal act is detected on the condition that the number of winnings in a predetermined time such as the big winning opening 28 within a predetermined time is equal to or more than a predetermined number. . However, the gaming state to which such a process can be applied is not necessarily limited to the big hit game or the small hit game.

  In the above-described embodiment, as an example of the illegal act detection process in the normal gaming state, the coil 8 generates an induced electromotive force, and the distance sensors 9a and 9b detect an object in the vicinity of the window portion 5. An example has been described in which an illegal act is detected on the condition that the detected state of illegal operation is detected a predetermined number of times or more within a predetermined time. However, the gaming state to which such processing is applicable is not necessarily limited to the normal gaming state.
