DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a malfunctioning radio wave detector for electronic equipment which detects a radio wave for performing an improper operation by malfunctioning the operation of electronic equipment. More specifically, the present invention is provided in a hall such as a game machine represented by a pachinko machine or a slot machine, a game medium cash exchange machine, and a non-contact IC card for game medium exchange using electromagnetic waves. The present invention relates to a malfunctioning radio wave detector that detects malfunctioning radio waves that cause various electronic devices to malfunction improperly.

2. Description of the Related Art A ball game machine such as a pachinko machine, a pinball game machine, a smart ball game machine, a game machine such as a slot machine, a game medium cash exchange machine arranged in a hall, and a game medium exchange game In non-contact IC cards, game operations and cash exchange operations are controlled by electronic circuits using IC chips. Normally, these electronic circuits include a central control unit (CPU) that performs general arithmetic processing and a storage element (RA) that can read and write data.
M), a storage element that can only read data (RO
M) and the like, and the CPU
Using the M and ROM, for example, a ball game machine manages winning balls and controls an accessory, and a slot machine controls operations of reels and the like.

[0003] However, the I used in the electronic circuit described above is
Since the C chip is easily affected by radio waves emitted from the outside, intentionally emitting an illegal radio wave in the vicinity of these electronic circuits to destroy the electronic circuit or cause the electronic circuit to malfunction. Such operations as illegally operate to illegally obtain a large amount of game media.

Conventionally, in order to prevent such an unauthorized operation, a countermeasure for preventing an unauthorized act by shielding the entire electronic circuit with a magnetic shielding member has been attempted. Although it is effective for radio waves emitted from aircraft, it is difficult to obtain a sufficient effect on radio waves emitted from high-power radios, so that measures against fraud were not sufficient.

[0005] Further, in order to prevent unauthorized operation by radio waves emitted from these high-output radios, attempts have been made to install equipment such as a sensor for detecting radio waves in a hall. Practical because new construction is required and equipment costs are required, and it reacts to radio waves emitted from in-store broadcasting radios and amateur radios, making it difficult to identify malfunctioning radio waves. It was not a target.

Therefore, a detector is installed in the hall and the IC
Unauthorized prize ball prevention that detects a radio wave of a required frequency that is likely to damage the chip and generates an alarm only when the electric field strength of the radio wave is equal to or higher than a predetermined value to notify that an illegal operation is being performed. An apparatus has been developed (Japanese Unexamined Patent Publication No.
284).

[0007]

However, in the above-described detector, the only radio waves that can be detected are radio waves having a specific frequency used as an unauthorized operation in the past and a predetermined electric field strength or more. When a new gaming machine with a developed electronic component is developed, a radio wave of a frequency that causes a malfunction with respect to the newly developed electronic component cannot be detected. When cheating takes place, the detector does not operate and there is a risk that the cheating may be overlooked. In addition, since the electric field strength detected by the detector varies greatly depending on the distance between the radio wave source and the detector, there are problems with the conventionally proposed detectors in terms of detection accuracy and the position of the detector. is there.

Further, the malfunction radio wave detector according to the present invention can notify the presence or absence of the malfunction radio wave by the notification means based on the detection result. As the notification means, for example, a lamp,
It can be at least one selected from sound, letters, voice, and vibration. Note that, in the present invention, electronic devices are devices provided with an electronic circuit using an IC chip or the like, and the IC chip or the like is destroyed by emitting a specific radio wave near these electronic devices. Or electronic devices that cause malfunction. In addition, as typical electronic devices, electronic devices arranged in a hall such as a game machine such as a pachinko machine and a slot machine, and a game medium cash exchange machine are exemplified, but are not limited thereto.

Radio waves that destroy or malfunction electronic circuits of electronic devices are received by antennas, which can be installed in halls. However, when a malfunction detector is incorporated in a mobile phone, Can also be used as a mobile phone antenna. The radio waves received by the antenna
Various radio waves having a wide band and different frequencies are included. For this reason, a known signal processing unit removes noise, which is an unnecessary frequency band, and forms it. The signal is formed corresponding to a plurality of frequencies, and the waveform pattern is signal-processed by a digital signal. Signal processing of the waveform pattern.

According to the present invention, in order to prepare in advance a comparison waveform pattern for detecting a radio wave causing a malfunction, for example, in the vicinity of electronic equipment such as a game machine or a game medium converter,
When radio waves of various frequencies in different bands are emitted, which destroys electronic circuits or causes malfunctions,
The waveform pattern of the operation signal is extracted as a malfunction waveform pattern, and this is stored in the waveform pattern storage means. The stored malfunction waveform pattern serves as one criterion for determining whether or not the newly received radio wave is a radio wave causing a malfunction.

According to the present invention, there is provided a waveform pattern learning means for analyzing and learning a characteristic of a waveform pattern which causes a malfunction in electronic devices and the like stored in the storage means. This learning means automatically analyzes a newly stored waveform pattern and a waveform pattern already stored in the storage means each time a waveform pattern causing a malfunction is newly stored in the storage means. Learn and find characteristic waveform patterns that appear in common.

In extracting a commonly appearing waveform pattern, various waveform processing techniques can be applied. For example, in the digital waveform processing, the duty ratio of the on / off signal, the generation pattern of the on / off signal, the appearance frequency of the repetitive waveform, and the detection of the pattern can be applied. In the analog waveform processing, it is possible to perform repeated signal extraction by applying an autocorrelation function, and perform waveform extraction by applying a cross-correlation function with a reference waveform pattern. When digital waveform processing is applied, a wide band can be supported by preparing a plurality of filters. When analog waveform processing is applied, the filter can be obtained by detecting the waveform shape as it is. It is possible to support a wide band without using. These waveform processing can be automatically performed by a computer, and the found waveform pattern is stored and stored as a comparison waveform pattern.

The learning effect of the learning means is improved as the amount of the waveform pattern stored in the storage means is increased. Therefore, in order to increase the accumulation amount of the waveform pattern to be analyzed and learned by the learning means, a configuration in which a waveform pattern similar to the waveform pattern extracted by the learning means is stored and accumulated in the storage means may be adopted.

The repetitive waveform pattern of the newly received radio wave is compared with various waveform patterns stored and stored in the storage means by the comparing means. This comparing means automatically compares the on / off occurrence state of both waveform patterns, the appearance frequency of the repetitive waveform, the pattern, and the like, and the waveform pattern of the newly received radio wave is the same as the comparison waveform pattern stored and accumulated; Alternatively, it is determined whether or not the waveform pattern is similar.

As a result of the comparison by the waveform pattern comparing means, the repetitive waveform pattern of the newly received radio wave is the same as the waveform pattern causing the malfunction which has already been stored and stored, or found by the waveform pattern learning means. If it is determined that it matches or is similar to the learning malfunction waveform pattern,
The received radio wave is determined to be an illegal radio wave that causes a malfunction. Therefore, for example, since there is a high possibility that an unauthorized operation has been performed in the hall, for example, the lamp of a dedicated portable device carried by an employee via a wireless communication line is turned on, or the display panel of the portable device is turned on. The staff will be notified by a notification means such as displaying characters on the display.

It should be noted that the malfunction radio wave detector for electronic devices according to the present invention can be incorporated in a commercially available mobile phone. When this configuration is adopted, the radio waves emitted in the hall can be simultaneously received by a plurality of staff members, so that the radio waves can be reliably detected without failing to receive the malfunctioning radio waves. In addition, using the communication function of the mobile phone, the detection result can be transmitted to the management center or a mobile phone having a function of receiving a transmission signal from the mobile phone. , Can contact the management center and the mobile phone.
