Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine for pachinko machines, pachislot machines and the like, which detects an illegal action using a radio wave or a magnet on a game machine. It concerns the device. 2. Description of the Related Art In recent years, it has been said that the total amount of damage to the game industry, such as pachinko machines, is tens of billions of yen per year due to fraudulent acts of exploiting balls using radio waves or magnets. Has been done. As a conventional device that detects such fraudulent activities, a detection circuit-type detection device that exclusively detects illegal radio waves and a magnet sensor or reed switch-type detection device that specifically detects illegal magnetic force are developed separately. Has been put to practical use. [0003] However, since the radio wave detecting device detects only fraudulent activities using radio waves, it cannot detect fraudulent activities using magnets. Also,
Since the magnet-compatible detection device detects only a fraudulent activity using a magnet, it cannot detect a fraudulent activity using radio waves.
Therefore, to detect both illegal radio waves and illegal magnetic force,
It is necessary to install both the detection device of the radio wave type and the detection device of the magnet type, and the installation space increases and the cost increases. In addition, since a radio wave receiving circuit type detection device also intercepts and reacts to radio waves transmitted from a mobile phone or the like, it cannot distinguish the radio waves transmitted improperly, resulting in erroneous detection. was there. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the ability to cope with both fraudulent acts using radio waves and magnets, and to accurately detect only radio waves transmitted illegally. Another object of the present invention is to provide a fraudulent activity detection device using a radio wave or a magnet for a gaming machine that can detect and detect a game machine. SUMMARY OF THE INVENTION Accordingly, the present invention provides an electrically conductive film sheet made of a transparent synthetic resin to which a pair of electrodes are connected, over a part or the whole area of the front face of a game machine. a sensor section made of an insulating material and or conductive material sticking was deposited on the entire surface between the pair of electrodes, a detection circuit for detecting an induced current generated between the pair of electrodes,
An unauthorized radio wave or magnetism detection circuit including a determination output circuit unit that determines and outputs an unauthorized radio wave or magnetism based on the detection value, and an unauthorized radio wave or magnetism is detected by the unauthorized radio wave or magnetism detection circuit. In a fraudulent activity detection device using a radio wave or a magnet for a gaming machine connected to an alarm device that generates an alarm, the sensor unit is a transparent plastic
Between the front and rear transparent pigs
Integrated with detection control board, two layers of gaming machine
It is characterized in that it can be inserted into the gap between the protective glasses . In the present invention, a conductive material for a magnetic sensor is attached to the front or back of a gaming machine such as a pachinko machine or a slot machine. As the conductive material, a surface-, band-, or line-shaped material subjected to a surface protection treatment can be used. The mounting position of the conductive material may be, for example, the back surface of the front glass of the gaming machine, the surface of the accessory or the liquid crystal screen, the ground surface or the back surface of the cell board, and may be a place invisible to the player if necessary. In short, any configuration may be used as long as an induced electromotive force is generated in the conductive material when an unauthorized magnet generator approaches within a predetermined proximity distance to the gaming machine. Magnetic generators include powerful magnets and radio generators (electromagnetic transmitters). A positive electrode and a negative electrode are connected to one end and the other end of the conductive material, and a fraudulent magnetism detection circuit for measuring the magnitude of the induced current (induced electromotive force) is formed between the two electrodes. . This is for detecting an induced current caused by the magnetism generated from the magnetic generator and detecting and determining whether or not the magnetic generator is an unauthorized means based on the detection result. And an alarm is connected to the illegal magnetism detection circuit,
If the detection circuit determines that the device is an illegal magnet generator, an alarm sound or an alarm lamp is immediately generated. The conductive material can be directly deposited on an insulator such as glass, or the surface of the conductive material can be coated with a protective sheet. In addition, a protective sheet is laminated on both front and back surfaces of the conductive material, and furthermore, the outer peripheral portions of the protective sheets on both sides are adhered to each other to perform a sealing protection process, so that dust, dust and moisture in the air can be applied to the conductive material. Adhesion can be prevented. When the conductive substance is in the form of a film sheet, an adhesive substance can be fused to the back surface of the sheet to adhere to the insulator. The detection principle of the present invention will be described. First, in the case of detecting a magnet serving as an illegal magnet generating means, when the magnet is brought close to the front of the game machine, as shown in FIG. An electromotive force is generated in the conductive material 46 on the gaming machine side. Therefore, a minute current in one direction flows between the pair of electrodes 47 at both ends of the conductive material 46. In this case, if the magnet 45 is moved away from the conductive material 46, a minute current is generated between the electrodes 47 in the opposite direction. Then, the intensity of the microcurrent increases as the magnetic force increases. By measuring the magnitude of the generated small current with the unauthorized magnetism detection circuit 48, it is detected that the magnet 45 has been brought close to the gaming machine, and an unauthorized gaming action can be easily determined. On the other hand, when the unauthorized magnet generating means is a radio wave generator with an antenna (electromagnetic wave transmitter), as shown in FIG. 14, a VHF is transmitted from the antenna 50 of the radio wave generator 49 to the front front of the gaming machine. Electromagnetic waves from the band to the microwave band are transmitted. Then, an electromotive force is generated in the conductive material 46 on the gaming machine side under the influence of the change in the induced electromagnetic field due to the electromagnetic wave. Therefore, a small current flows between both electrodes 47 of the conductive substance 46. The intensity of this minute current increases as the electromagnetic wave becomes stronger. By detecting the flowing small current with the unauthorized magnetism detection circuit 48, it is detected that the electromagnetic wave has been transmitted to the gaming machine.
In this case, it is necessary to determine whether or not the source of the electromagnetic wave is an unauthorized device, but by measuring the magnitude of the output value of the microcurrent, the source is the unauthorized radio wave generator 49, or It is easy to determine whether the mobile phone is a legitimate mobile phone, an in-store transceiver, a wireless microphone, or the like. That is, the present apparatus can reliably detect only the transmission electromagnetic wave from the unauthorized radio wave generator 49. As described above, according to the present invention, when an unauthorized radio wave generator or a magnet is approached within a predetermined distance on the front side of the gaming machine, an electromotive force is generated in the conductive substance, and a current flows. The current value is measured by a fraudulent magnetic detection circuit.
Then, if the measured value of the current is within the predetermined range, it is determined that an illegal act has been performed using an illegal magnetic generating device. When a fraudulent activity is determined, a warning sound or a warning light is immediately emitted by the alarm device. [0010] Therefore, by using the fraud detecting device of the present invention, it is possible to detect both the use of the unauthorized radio wave generator and the use of the magnet by one device, and thus the mounting space can be reduced. , And significant cost reduction can be achieved. In addition, when detecting an illegal radio wave, the magnitude of the measured current value enables accurate determination of a legitimate radio wave generated from a mobile phone. There is no risk of erroneous detection and determination. Next, an embodiment of the present invention will be described with reference to an embodiment shown in the drawings. In this embodiment, a conductive film sheet made of a transparent synthetic resin is attached to the front or back side of the pachinko machine, and a fraudulent magnetic detection circuit is formed between a pair of electrodes connected to both ends of the film sheet, The magnitude of the electromotive force generated due to the change in is measured. Further, an alarm device is connected to this circuit, and when an illegal magnetism is detected, an alarm is activated so that an illegal player can be immediately identified.

FIG. 10 is an exploded perspective view of FIG. 9, and FIGS. 11 and 12 are cross-sectional views showing another example of the structure of the conductive film sheet according to the present invention. As shown in FIG. 2, reference numeral 1 denotes a pachinko machine, and 2 denotes a cell panel which constitutes a front portion of the cell panel. A glass section 3 is attached to the front side of the cell panel 2 so as to be openable and closable. On the back side of the glass part 3, a two-layer protective glass body 4 is attached,
The two-layer protective glass body 4 has a front glass part 5 and a back glass part 6.
Consists of A gap of about 9 mm is formed between the front glass part 5 and the back glass part 6, and about 8 m
An m-thick planar magnetic sensor 7 is inserted. The magnetic sensor 7 detects the occurrence of illegal magnetism due to the use of a magnet or the like. That is, when the player brings the radio wave generator 8 or the strong magnet 9 close to the pachinko machine 1, a small current flows through the magnetic sensor 7. As shown in FIG. 3, the magnetic sensor 7 includes a conductive film sheet 11 made of a transparent synthetic resin, which is disposed on the front surface of the cell board 2 and induces electromotive force by a change in magnetism, and a detection structure integrally formed on the rear surface side. A control board (attachment board for unauthorized magnetic detection circuit) 12;
An LED warning indicator light 13 is provided. The detection control board 12 is integrated with a sandwich structure sandwiched between a transparent plastic front cover 14 and a transparent plastic back cover 15. Here, as the conductive film sheet 11, a transparent conductive film (e.g., trade name: High Beam: manufactured by Toray Industries, Inc.) obtained by depositing indium tin oxide or the like on the surface of a biaxially stretched polyester film by a sputtering method is used. I have. A pair of positive and negative electrodes 18 and 19 are connected to the left and right ends of the conductive film sheet 11 via electrode extension film cords 17 penetrating the detection control board 12. The pair of electrodes 18 and 19 can be fixedly attached to the rear side of the cell board 2 as shown in FIG. Usually, the mounting positions of the electrodes 18 and 19 are not particularly limited as long as they are appropriate positions inside the pachinko machine 1.
For example, the electrodes 18 and 1 are located near the conductive film sheet 11 or the accessory 21 or near the back surface of the glass portion 3.
9 can be attached (see FIGS. 5 to 9). Since the conductive film sheet 11 of the fraudulent magnetic detector 7 is a flexible sheet material, it can be freely formed into a required shape by die cutting. Therefore, the outer shape of the conductive film sheet 11 can be die-cut into the same shape as the plastic frame 22 of the cell board 2, and this can be directly fixed and used as a base sheet material of the plastic frame 22. . For example, after the conductive film sheet 11 is die-cut into a predetermined shape, FIG.
Alternatively, as shown in FIG.
1 can be screwed and fixed to all or a part of the base region of the plastic frame 22. As shown in FIGS. 7 and 8, the conductive film sheet 11 can be attached to the entire front surface of the accessory 21 and the entire front surface of the liquid crystal screen 24. 5 to FIG.
Reference numerals 25 and 26 in the drawing denote a die cut portion and a screw hole cut portion of the conductive film sheet 11, respectively. Here, the structure of the conductive film sheet 11 will be described. 9 and 10 show an example in which a protective sheet 2 is provided on the surface of a square conductive film sheet 11.
7, the insulating film 28 made of glass, bakelite resin, acrylic resin, or the like is adhered to the back surface of the conductive film sheet 11, and the left and right edges of the conductive film sheet 11 extend parallel to each other. Strip-shaped electrode 18,
19 is pasted. In addition, the structural example of FIG.
On both the front and back surfaces of the conductive film sheet 11, the edges extend outside the sheet, and the protective sheet 30, the lower protective sheet 3
1, the conductive film sheet 11 is hermetically protected by laminating the outer extending portions of the protective sheets 30 and 31 with each other. Further, the structure example of FIG. 12 shows that the conductive material 11 is placed on an insulating sheet 32 such as glass.
Is directly vapor-deposited, and a surface protection sheet 33 is adhered thereon. As shown in FIG. 1, between the two electrodes 18 and 19 of the magnetic sensor 7, there is formed an unauthorized magnetism detecting circuit 35 for measuring the magnitude of the induced current (induced electromotive force). The unauthorized magnet detection circuit 35 detects and determines an unauthorized radio wave generator 8 or the like based on the magnitude of the induced current due to magnetism. The configuration of the illicit magnetism determination circuit 35 includes a detection circuit section 36 for measuring the magnitude of the induced current, an amplification (reduction) circuit section 37 for adjusting the detection level of the measurement value, and a magnitude of the level-adjusted measurement value. And an output circuit unit 38 for judging and outputting an incorrect magnetism based on the output. Output circuit 3
8 is provided with reset means 39 for resetting the output value. An alarm 41, here, an alarm buzzer 42, a light-emitting LED alarm indicator 13, and the like are connected to the unauthorized magnet determination circuit 35. Thus, when the occurrence of illegal magnetism by the radio wave generator 8 or the like is determined by the illegal magnetism detection circuit 35, the alarm 41 is activated, and an alarm sound and an alarm light are automatically generated. I have. At the same time as the operation of the alarm 41, the power of the pachinko machine 1 may be cut off to automatically stop the game. Next, a description will be given of a method of detecting illegal magnetism by the present embodiment. As shown in FIG. 1, the unauthorized player now approaches the glass part 3 of the pachinko machine 1 from the front in front of the illegal powerful magnet 9, and the strong force is applied within a predetermined distance to the conductive film sheet 11 on the front side of the pachinko machine 1. Assume that the magnet 9 has moved. Then, in the conductive film sheet 11 on the glass part 3 side, an electromotive force is generated due to the influence of the lines of magnetic force emitted from the strong magnets 9, so that a minute current flows in one direction between the electrodes 18 and 19. The value of the microcurrent increases as the magnetic force (magnetic flux density) emitted from the strong magnet 9 increases. The generated small current is detected by the detection circuit unit 36 of the unauthorized magnetic detection circuit 35.
The level of the detection result is adjusted by the amplifier circuit unit 37. Thereafter, the output circuit section 38 determines and outputs that the strong magnet 9 has approached the glass section 3 based on the detected value of the minute current. That is, by measuring and determining that the output value of the weak current is within the predetermined range, it is determined whether or not the illegal action using the strong magnet 9 is performed. The alarm buzzer 42 and the light-emitting LED
The warning indicator light 13 is activated, and a clerk or the like is immediately notified. On the other hand, when an unauthorized radio wave generator 8 is approached within a predetermined distance from the glass part 3 of the pachinko machine 1, the conductive film sheet 11 of the magnetic sensor 7 attached to the glass part 3 generates a radio wave. Electromagnetic induction occurs due to the effect of the electromagnetic waves emitted from the vessel 8, and a minute current flows between the electrodes 18 and 19. The value of the microcurrent increases as the electric field strength of the electromagnetic wave increases. The flowing microcurrent is the same as above.
It is output from the output circuit unit 38, and it is detected from the output value that a radio wave has been transmitted to the pachinko machine 1. In this case, it is necessary to determine whether or not the transmitted radio wave is unauthorized. This determination is made by measuring the magnitude of the output value of the minute current, and thereby determining whether the illegal radio wave generator 8
Or other legal communication equipment, that is, a mobile phone, an in-store transceiver, a wireless microphone, or the like, can be discriminated, and only unauthorized radio waves can be reliably detected. That is, only the unauthorized radio wave generator 8 can be accurately determined depending on whether or not the magnitude of the measured value is within a predetermined range or more. In the apparatus of the present embodiment, one radio wave generator 8
Unauthentic radio waves and magnetism can be detected for both the strong magnet 9 and the strong magnet 9. In particular, by detecting the magnitude of the measured value of the induced current, it is possible to accurately determine whether or not the radio wave transmission source is an unauthorized device. There is no danger of false detection as a radio transmitter. It should be noted that the present invention is not limited to the above-described embodiment, and various application modifications are possible. In the above embodiment, the conductive film sheet is used as the conductive material. Alternatively, a material in which a metal foil is attached to a material such as a fiber may be used. The present invention is also applicable to the use of illegal radio waves for other electronic devices that malfunction due to illegal radio waves, such as vending machines. [0023] According to the present invention, illegal against the gaming machine
Fool that can respond to both fraudulent acts using radio waves and magnets
However, there is an excellent effect that these can be reliably detected .
