  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  FIG. 1 shows an external view of a ball game machine according to an embodiment of the present invention. This bullet ball game machine 1 is a so-called feather object classified into two types in the old wind management law. However, the present invention can also be applied to a ball game machine other than a feather object.

  The board surface 21 (FIG. 2) of the winged ball game machine 1 has, for example, a chucker 11-1 in which the wing 13 is opened only once when the game ball enters, and the wing 13 when the game ball enters. For example, a chucker 11-2 that is opened only twice, a characteristic product for each model is provided, and an accessory 12 that generates a lot of prize balls (game ball payout) in response to the entry of a game ball, In addition, a blade 13 that guides the game ball to the accessory 12 by being opened and closed at a predetermined timing is provided. Inside the accessory 12 is a V zone 14 that is a big hit when a game ball enters.

  Hereinafter, the chuckers 11-1, 11-2, the accessory 12, the V zone 14, and the like are collectively referred to as a winning opening, and a game ball entering the winning opening is described as winning.

  The jackpot means that it is easy to guide the game ball into the accessory 12 by repeatedly opening and closing the blades 13 until a predetermined period elapses or until a predetermined number of game balls wins the accessory 12. Refers to the state.

  In the case of a big hit, the player can expect to get many prize balls. Therefore, it is expected that a player who performs cheating tries to displace the path of the game ball illegally by applying external force so that the game ball wins the V zone 14 in the accessory 12.

  Therefore, if an illegal displacement of the course of the game ball in the vicinity of the V zone 14 is detected, it becomes easy to detect an illegal act by the player. Based on this idea, the game ball displacement sensor 23 (FIG. 2) that detects an illegal displacement of the path of the game ball is a position close to the V zone 14, such as the mounting position 16 illustrated by a broken line. Then, as shown in FIG.

  However, the mounting position of the game ball displacement sensor 23 is not limited to the mounting position 16, and for example, an illegal displacement on the back surface of the accessory 12 or the path of the game ball such as the chuckers 11-1 and 11-2. It is good also as the back side of the position where is likely to occur. Or you may make it attach to the front side of a board surface. Further, a plurality of game ball displacement sensors 23 may be attached.

  FIG. 3 shows an example of an electrical configuration inside the ball game machine 1.

  The ball game machine 1 is connected to a game ball displacement sensor 23 that detects an illegal displacement of the path of the game ball, a main control unit 31 that controls the entire ball game machine 1, and a hall computer 41 to send a predetermined signal. An external interface (I / F) 32 for communication, a voice control unit 33 for outputting sound from the speaker 34 in response to a game ball winning, a liquid crystal display or the like corresponding to a game ball winning, etc. A symbol display unit 36 that changes the screen display of the symbol display unit 36 provided inside, and a lamp control unit 37 that blinks the illumination lamp 38 received also on the board surface 21 in response to winning of a game ball, etc. Is done.

  Each ball game machine 1 installed in a game store (so-called pachinko store) is connected to a hall computer 41 provided for management of the game store. Information such as the occurrence of an action is notified to the hall computer 41. The hall computer 41 includes a display unit 42 that visually displays the status of each ball game machine 1 and a warning unit 43 that notifies a user (such as a store clerk of a game store) of the occurrence of an illegal act by the player. Yes.

  When an illegal displacement is detected in the course of the game ball by the game ball displacement sensor 23, the game ball displacement sensor 23 outputs a detection signal indicating that to the main control unit 31. Based on the detection signal from the game ball displacement sensor 23, the main control unit 31 determines the presence or absence of fraud, and notifies the hall computer 41 of the fraud detection signal indicating the determination result via the external I / F 32. To do. The hall computer 41 responds to the notification of the fraud detection signal from each ball game machine 1 and controls the warning unit 43 to notify the user of the occurrence of the fraud.

  Next, a configuration example of the game ball displacement sensor 23 will be described with reference to FIGS. FIG. 4 is an external view of the game ball displacement sensor 23, FIG. 5 is an exploded view of the game ball displacement sensor 23, and FIG. 6 is a cross-sectional view of the game ball displacement sensor 23.

  The game ball displacement sensor 23 has a metal ball 51 having the same weight and size as the game ball, an upper cover 52, a case 53 having a concave bottom, and the amplitude of the high frequency signal corresponding to the displacement of the metal ball 51. The coil 54 is made to change, the calculating part 55 produces | generates a detection signal based on the amplitude fluctuation | variation of a high frequency signal, and the lower cover 56. However, the weight and size of the metal ball 51 may not be exactly the same as those of the game ball.

  The metal sphere 51 is disposed in a case 53 having a concave bottom 71. As shown in FIG. 7, the positional relationship between the metal sphere 51, the coil 54, and the concave bottom 71 is such that the metal sphere 51, the coil 54, and the concave bottom 71 are each in a stationary state. The central axes are made to coincide.

  Therefore, in the vicinity of the game ball displacement sensor 23, if there is no illegal displacement in the path of the game ball, the metal ball 51 is not displaced while being placed in the center of the concave bottom 71, but the path of the game ball is incorrect. When a large displacement occurs, the metal ball 51 has the same weight and size as the game ball, so that it is displaced on the concave bottom 71 and then returns to the center of the concave bottom 71 as with the game ball. become.

  Next, the calculation unit 55 that generates a detection signal based on the amplitude fluctuation of the high-frequency signal by the coil 54 corresponding to the displacement of the metal sphere 51 will be described with reference to FIGS. 8 to 10. 8 shows a functional configuration example of the calculation unit 55, and FIG. 9 shows a specific circuit diagram.

  The calculation unit 55 generates a high-frequency signal and outputs the high-frequency signal to the coil 54. The high-frequency oscillation unit 81 oscillates a high-frequency signal whose amplitude is changed by the displacement of the metal sphere 51 in the vicinity of the coil 54. The amplitude of the high-frequency signal A peak detector 82 for generating a peak signal indicating the fluctuation of the AC, an AC amplifier 83 for generating a differential signal indicating the speed of amplitude change of the high-frequency signal by differentiating the peak signal, and comparing the differential signal with a predetermined threshold. Based on the output of the comparison unit 84 and the comparison unit 84, the output unit 85 outputs a detection signal indicating that an illegal displacement has occurred in the course of the game ball.

  Next, the operation of the ball game machine 1 in which the game ball displacement sensor 23 is installed will be described with reference to the flowchart of FIG.

  In step S <b> 1, a high frequency signal is oscillated by the high frequency oscillation unit 81, and the oscillated high frequency signal is output to the coil 54 and the peak detection unit 82. The coil 54 generates a high frequency magnetic field corresponding to the high frequency signal. When an external force is applied to the ball game machine 1 by an unauthorized player, and an unauthorized displacement occurs in the course of the game ball, the metal ball 51 of the game ball displacement sensor 23 is also displaced, and the metal ball The displacement 51 affects the high-frequency magnetic field of the coil 54, and this effect appears in the amplitude change of the high-frequency signal as shown in FIG. 11A.

  Since the high-frequency signal whose amplitude has changed is input to the peak detection unit 82, in step S2, the peak detection unit 82 generates a peak signal indicating amplitude fluctuation as shown in FIG. 11B. The generated peak signal is output to the AC amplifier 83. In step S3, the AC amplification unit 83 differentiates the peak signal to generate a differential signal indicating the speed of the amplitude change of the high frequency signal as shown in FIG. 11C. The generated differential signal is output to the comparison unit 84.

  In step S4, the comparison unit 84 compares the differential signal with a predetermined threshold value set in advance, and outputs a comparison result as shown in FIG. 11D to the output unit 85. In the output unit 85, if it is determined that the differential signal is larger than the predetermined threshold based on the comparison result of the comparison unit 84, the process proceeds to step S5, and the path of the game ball as shown in FIG. A detection signal indicating that a significant displacement has occurred is generated. This detection signal is output to the main control unit 31, and the main control unit 31 determines whether or not fraudulent activity has occurred based on this detection signal, and sends a fraud detection signal indicating the determination result via the external I / F 32. Notify the hall computer 41. The hall computer 41 responds to the notification of the fraud detection signal from each ball game machine 1 and controls the warning unit 43 to notify the user of the occurrence of the fraud.

If it is determined in step S4 that the differential signal is not greater than the predetermined threshold based on the comparison result of the comparison unit 84, the process returns to step S1 and the subsequent processes are repeated.

  Above, description of operation | movement of the ball game machine 1 in which the game ball displacement sensor 23 is installed is complete | finished.

  According to the ball ball game machine 1 in which the game ball displacement sensor 23 described above is installed, the ball ball game machine 1 is launched by applying an external force that strikes, shakes, or tilts the ball game machine 1 from an unauthorized player. It is possible to accurately detect without misdetection that the path of the game ball is illegally displaced and guided to the winning a prize opening.

  Further, for example, even when an unauthorized player moves the path of a game ball launched by bringing a magnet close to the ball game machine 1, the metal ball built in the game ball displacement sensor 23 is used. Since the amplitude of the high-frequency signal changes even if the metal ball 51 is displaced or the metal ball 51 is not displaced, such an illegal act can also be detected.

  Next, a modified example of the game ball displacement sensor 23 will be described.

  FIG. 12 shows an example in which a coil bobbin 91 made of a ferromagnetic material is added to the center of the coil 54. By adding the coil bobbin 91, the direction of the magnetic flux generated by the coil 54 is directed in the direction of the metal sphere 51, so that the displacement of the metal sphere 51 can be detected with higher accuracy as the amplitude change of the high-frequency signal. .

  FIG. 13 shows an example in which the single coil 54 is changed to a double, that is, an example in which coils 54-1 and 54-2 having the same central axis are provided instead of the coil 54. If the coils are doubled and the amplitude of the high-frequency signal changed by each is detected, the displacement amount (movement amount) of the metal sphere 51 can also be detected. Note that the coils 54 may be further increased to three or more layers. Moreover, as shown in FIG. 12, a coil bobbin made of a ferromagnetic material may be provided as a winding axis of each coil.
