[First Embodiment]
An embodiment in which the present invention is applied to a pachinko gaming machine will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, a game area R1 is formed on the front surface of the game board 11 of the game machine 10 of the present embodiment, and a plurality of winning openings 14A, 14B, 15, 20 are provided in the game area R1. There is. Inside each of the winning openings 14A, 14B, 15 and 20, a detection sensor (not shown) for detecting the winning of a game ball is attached, and on the back side of the game board 11, various types are detected based on the signals of the detection sensors. A main control board or the like (not shown) is provided for controlling the entire game such as determining whether or not the game is won and switching the game state based on the result of the game. Further, the game board 11 is provided with a fraud detection sensor 30 for detecting a fraudulent activity (so-called radio wave goto) on the detection sensor by a radio wave.

  The fraud detection sensor 30 includes a circuit board 31 shown in FIG. 2 inside a resin case (not shown). A loop antenna 33, a current measuring unit 34, etc. are mounted on the circuit board 31, and they are connected by a printed wiring or the like to form a detection circuit 32. The loop antenna 33 corresponds to the “noise receiving unit” of the present invention and can receive the wireless noise in the direction orthogonal to the circuit board 31. The current measuring unit 34 corresponds to the “current detecting unit” of the present invention, and measures the current flowing through the detection circuit 32. Further, the current measuring unit 34 is connected to the CPU (not shown) of the main control board, and the current value measured by the current measuring unit 34 is fetched by the CPU. The CPU executes a fraud detection process described below every predetermined period, and determines whether the received wireless noise is fraudulent noise based on the measured current value. The CPU that is executing the fraud detection process corresponds to the “fraud determination means” of the present invention.

  By the way, the detection circuit 32 of the present embodiment is provided with an opening / closing member 38 that switches the detection circuit 32 from the closed state to the open state when an unauthorized magnetic force or vibration is applied from the outside. The opening / closing member 38 is supported by a support piece 36 protruding from the upper surface of the circuit board 31. The support piece 36 has an L-shape, and includes a leg portion 36A extending in a direction orthogonal to the upper surface of the circuit board 31, and a cantilever portion 36B bent at a right angle from the tip end portion of the leg portion 36A. A compression coil spring 37 is swingably fixed to the tip of the cantilever portion 36B and hangs down from the cantilever portion 36B, and an opening / closing member 38 is attached to the lower end of the compression coil spring 37.

  The opening / closing member 38 has a strip shape and is formed by attaching an iron foil 38B to a position near the lower end of a sheet-shaped conductive film 38A that is elastically deformable. Further, as shown in FIG. 2, the opening / closing member 38 has a length such that the lower end thereof is in contact with the upper surface of the circuit board 31 in a state of being suspended from the compression coil spring 37. A magnetizing member 39 is arranged in a lower region of the detection circuit 32 where the opening / closing member 38 hangs down. As a result, the opening / closing member 38 is always positioned at the closed position where the surface on the side on which the iron foil 38B is adhered by being biased by the magnetizing member 39 is in contact with the magnetizing member 39, and the detection circuit 32 is It is in a closed state where current can flow.

  Further, since the compression coil spring 37 can be constructed with a relatively small size and the opening / closing member 38 is formed of a film, the compression coil spring 37 and the opening / closing member 38 can be made light in weight, and the compression coil spring The magnetic force of the magnetizing member 39 can be increased as compared with the gravity applied to the opening 37 and the opening / closing member 38. Thereby, for example, when the circuit board 31 is arranged vertically and the opening / closing member 38 is not affected by the magnetic force from the magnetizing member 39, the opening / closing member 38 and the compression coil spring 37 hang down in the vertical direction, and Even if the lower end is separated from the magnetizing member 39, when the opening / closing member 38 is affected by the magnetizing member 39, the opening / closing member 38 is pulled toward the magnetizing member 39 against gravity. The lower end of the opening / closing member 38 comes into contact with the magnetizing member 39, and the compression coil spring 37 and the opening / closing member 38 are bridged between the cantilever portion 36B and the magnetizing member 39, and the detection circuit 32 is closed. It becomes possible. That is, in the fraud detection sensor 30 of the present embodiment, the fraud detection sensor 30 can be attached to the game board 11 at any angle, and the degree of freedom in installing the fraud detection sensor 30 can be increased. The magnetizing member 39 corresponds to the “biasing means” of the present invention, and the magnetizing member 39, the support piece 36, and the compression coil spring 37 constitute the “opening / closing support mechanism” of the present invention.

  A battery 35 (corresponding to the “reference current generating means” of the present invention) that allows a preset reference current to flow is mounted on the detection circuit 32. Accordingly, when the detection circuit 32 is in the closed state, the reference current is flowing in the detection circuit 32. When the wireless noise is detected in this state, the reference current and the current according to the magnitude of the wireless noise are changed. The sum of will flow.

  As described above, the CPU of the main control board executes the fraud detection process every predetermined period. In the fraud detection process, it is determined whether or not fraud is performed based on the current value measured by the current measuring unit 34. Specifically, when the measured current value is equal to or higher than a predetermined reference current, a determination is made that an injustice has occurred, and an abnormality is reported. Further, even when the measured current value is 0, that is, when the detection circuit 32 is in an open state in which no current flows, it is determined that the fraudulent operation is performed and the abnormality is notified.

  This concludes the description of the configuration of the present embodiment. Next, the function and effect of this embodiment will be described. When a game ball is won in each of the winning openings 14A, 14B, 15 and 20, a detection sensor provided inside each of the winning openings 14A, 14B, 15 and 20 detects the passage of the gaming ball and sends a signal to the main control board. To send.

  By the way, there is a fraudulent act of irradiating the detection sensor with an electric wave from the outside to make the player mistakenly think that the game ball has passed, even though the game ball has not passed, and obtain the prize ball illegally. It may be done. Further, the illegal acts include not only those using radio waves but also those using magnetic force or vibration.

  On the other hand, since the gaming machine 10 of the present embodiment is provided with the fraud detection sensor 30, these fraudulent acts can be detected. Specifically, for example, when the detection sensor is irradiated with a radio wave, a current corresponding to wireless noise flows in the detection circuit 32 of the fraud detection sensor 30, so that the current measuring unit 34 performs the fraud detection process. It is determined that the injustice is performed based on the measured current value, and the abnormality is notified.

  Further, for example, when a magnetic force is applied to the detection sensor from the outside, the opening / closing member 38 in the fraud detection sensor 30 is attracted by the magnetic force from the outside and moves away from the magnetizing member 39 to the open position. The detection circuit 32 is opened. Then, based on the measured value of the current measuring unit 34 being 0, it is determined that the fraud detection process is fraudulent, and the abnormality is notified.

  Further, for example, when vibration is applied to the gaming machine 10 from the outside, the compression coil spring 37 swings in the fraud detection sensor 30 and the opening / closing member 38 moves to an open position apart from the magnetizing member 39. , The detection circuit 32 is opened. Then, based on the measured value of the current measuring unit 34 being 0, it is determined that the fraud detection process is fraudulent, and the abnormality is notified.

  As described above, in the gaming machine 10 of the present embodiment, the fraud detection sensor 30 capable of detecting fraud caused by radio waves can also detect fraud caused by magnetic force or vibration based on the detection result of the current measuring unit 34. That is, according to the present invention, since the current measuring unit 34 can be used not only for detecting unauthorized wireless noise but also for detecting unauthorized magnetic force and vibration, it is easy to secure a space and further reduce the cost. Is possible.

  Further, in the present embodiment, since the detection circuit 32 is provided with the battery 35, it is possible to easily determine whether the detection circuit 32 is in the closed state and no wireless noise is detected, or the detection circuit 32 is in the open state. You can

  Furthermore, in this embodiment, since the opening / closing member 38 can be swung in three dimensions, the direction of detectable vibration can be set in three dimensions. Further, by providing the compression coil spring 37, it is possible to easily detect vibration, and it is possible to improve the accuracy of fraudulent detection related to vibration.
