【Example】

[Embodiment 1] Next, an embodiment of a radio wave sensor system according to claim 1 of the present invention will be described with reference to FIGS. The radio wave sensor 100 shown in FIG. 1 is installed near a ROM board inside a pachinko machine, for example, in a pachinko parlor. As a result, if someone emits an illegal radio wave in an attempt to upset the control inside the pachinko machine, the radio wave receiving means 10
1 receives the radio wave and outputs the radio wave as an alternating current. The output current is converted into a DC current by the rectifier 102. Then, for example, the control means 200 installed in the office of the pachinko parlor processes the DC current from the rectification means 102 by the CPU 204 via the input / output unit 206 and the A / D conversion unit 205, and outputs a predetermined current value. If the current value exceeds a predetermined current value, it is determined that the current value is abnormal. When the CPU 204 determines that there is an abnormality, the CPU
Is transmitted to the display unit 201, and the display unit 201 transmits the predetermined information (L
ED lighting, letters, etc.), whereby it is possible to know that an office worker is about to perform some kind of fraud on the pachinko machine. Furthermore, CPU
An abnormal signal is transmitted from 204 to an alarm output unit 203, and the alarm output unit 203 outputs an alarm to an external monitoring center or the like,
A fraudulent act can be dealt with by dispatching a response person from a monitoring center or the like.

The display unit 201 and the audio output unit 2
02. It is not necessary to perform all the operations of the alarm output unit 203, and at least one of them may be operated as needed. [Embodiment 2] Next, a radio wave sensor system according to claims 2 and 3 of the present invention will be described with reference to FIGS. 2, 3 and 4. FIG.

As in the first embodiment, for example, a radio wave sensor 110 shown in FIG. 2 is installed near a ROM board inside a pachinko machine. Thus, when someone emits an illegal radio wave to the pachinko machine, the radio wave receiving means 101 receives the radio wave and converts the radio wave into an alternating current, and the alternating current is converted into a direct current by the rectifying means 102. You. The applied voltage of the same predetermined value which is proportional to the intensity of the electromagnetic wave input from radio receiving section 101 to the negative terminal of the comparison unit C1~ comparing portion C5 of the circuit means 103 through l ₆ by direct current from the rectifying means 102 Is done.

Further, the control unit 200 is for supplying a predetermined voltage through l _7, resistors R5, the resistor R4 · · · resistor R1 compare unit C5 a reduced voltage by sequentially voltage drop across, comparator unit C4 · ..Applied to the plus terminal of the comparison section C1. In this configuration, when all the minus voltages of the five comparators C1 to C5 in the circuit means 103 are lower than the plus voltage, the outputs of the comparators C1 to C5 become high, no current flows in the direction indicated by Oyobi in FIG. 2, the current flows only in the display means 6 through l _9. Therefore, it can be confirmed from the display on the display means 6 that a normal current is flowing from the control means 200 to the radio wave sensor 110.

Now, it is assumed that the radio wave receiving means 101 has received a radio wave. The radio waves are weak, and the rectifying means 102
When the voltage supplied to the minus side of the comparison unit C5 is lower than the voltage supplied to the plus side, the output of each of the comparison units C1 to C5 becomes high, and the external circuit connected thereto is not driven. . That is, the current does not flow through each of the resistance means 1 to 5 and the current flowing through the display means 6 does not change, and the control means 200 controls the display unit 201 and the alarm output unit 2.
No warning signal or the like is output to the control signal 03. Therefore, even if there is a person who uses a mobile phone or the like at a certain distance from the pachinko machine, the radio wave sensor 110 does not operate due to radio waves emitted from the mobile phone.

For example, the voltage supplied from the rectifier 102 to the minus side of each comparison unit by the radio wave received by the radio wave reception unit 101 is higher than the plus side voltage of the comparison unit C1,
When the voltage is lower than the positive voltage of the other comparison units C2 to C5, only the comparison unit C1 outputs a low signal. At that time, since the higher voltage supplied to the negative side of the comparator unit C1 through l ₈ from the control unit 200 than the voltage supplied to the positive side of the comparator unit C1, l ₈ in the direction of in FIG A current flows through the resistance means 1 through the resistance means 1. At that time, a current flows from the control means 200 to the display means 6 and the resistance means 1, and the current flowing from the control means 200 increases more than when no current flows through the comparison section C1. The control unit 200 recognizes the increase in the current, and can recognize that the comparison unit C1 is electrically connected to the resistance unit 1 which is an external circuit. Similarly, as the intensity of the radio wave received by the radio wave receiving unit 101 increases, the resistance unit 2, the resistance unit 3, and the resistance unit 4 are transmitted through the comparison unit C1, the comparison unit C3, the comparison unit C4, and the comparison unit C5 in addition to the comparison unit C1. Since the current flows through the resistance means 5, the control means 200 can indirectly recognize the number of comparison parts electrically connected to the external circuit by measuring the current value. Therefore, for example, in the case of a pachinko machine which is easily affected by radio waves, the control unit 200 is set so as to determine an abnormality when the comparison unit C2 is electrically connected to the external resistance means 2, and the influence of the radio waves is reduced. In the case of a pachinko machine which is difficult to receive, when the comparison section C4 is electrically connected to the external resistance means 4, the control means 20
If 0 is determined to be determined to be abnormal, the criteria for determining an abnormality can be appropriately set according to the degree of susceptibility to radio waves.

Although the effects of radio waves are not uniform because the components, wiring, various sensors, and the like of pachinko machines are different from each other, according to the radio wave sensor system of the present invention, the characteristics of the pachinko machines with respect to radio waves are considered. Control means 20
It can be easily dealt with only by changing the reference of the current value that the CPU 204 judges to be abnormal at 0, and does not require cumbersome work.

Also, when the radio wave receiving means 101 is not receiving radio waves, since a minute current flows from the control means 200 to the display means 6, the control device 200 and the radio wave sensor 11
If the wire between 0 and 0 is disconnected, the current value becomes zero, so that the control unit 200 can recognize the disconnection. Further, even when the wiring is short-circuited on the control means 200 side, the current value increases, so that the short-circuit can be detected. Third Embodiment A radio wave sensor system according to a fourth embodiment of the present invention will be described with reference to FIGS.

In this embodiment, the radio wave sensor 1 shown in FIG.
Each of the resistance units 1 to 5 in 10 is a display unit, for example, an LED, and the other configuration is the same as that of the second embodiment. In this case, since it is possible to visually know that a current flows through each LED, it is possible to know the presence of an illegal radio wave at the installation position of the radio wave sensor 110,
Further, an operation check test of the radio wave sensor can be easily performed.

Incidentally, a plurality of radio wave sensors may be connected to one control means. At this time, as long as there is no problem in operation, a plurality of radio sensors may be simply connected to the control means for one control means, or a method of periodically polling using a switch, Alternatively, a plurality of radio sensors may be connected to the control means using a known address unit that outputs an address signal unique to the radio sensor.

The radio wave sensor system of the present invention can be applied not only to pachinko machines but also to other game machines such as pachislot machines. It can be applied as appropriate.

[0023]

As described above, according to the radio wave sensor system of the present invention, by controlling the current value or voltage value of the radio wave sensor on the control means side, an illegal radio wave for a game machine such as a pachinko machine can be transmitted. Can be detected. In addition, even if the effects of radio waves differ depending on the amusement machine, by providing at least one comparison unit in the circuit means, the control means can easily change the standard of the current value determined to be abnormal. And no cumbersome work is required.

Further, by providing display means for displaying a part of the voltage supplied from the control means, even if the wiring between the control means and the radio wave sensor is short-circuited, it can be easily detected and the display means can be viewed. Thereby, it can be visually confirmed that the radio wave sensor system is operating normally. In addition, by using the resistance means corresponding to each comparison unit in the circuit means as a display means, it is possible to visually know on the radio wave sensor side that an illegal radio wave is being generated, and a confirmation test of the radio wave sensor Can also be easily performed.
