はできる。According to the present invention, when a game machine is transported and carried into a game arcade such as a pachinko parlor, each component constituting the game machine during the transportation (in particular, a ROM which is a center of control of the game machine).
One purpose is to detect fraudulent acts that transform a user into a fraudulent product. And the gaming machine stands on the bed of the car.
It will be transported in a state where it is placed in an aligned state. Therefore, when an attempt is made to cheat a gaming machine placed on this bed, an operation of tilting the gaming machine or lifting the gaming machine occurs as a pre-process. Therefore, during the transportation, the gaming machine is extremely tilted, or vibration accompanying the operation of lifting the gaming machine is generated, so that it is detected by predetermined detecting means, and determined by the determining means based on the output of the detecting means. , It is possible to determine the presence or absence of wrongdoing. In addition, not only during transportation but also in a state where the device is installed in a game arcade, it is possible to determine the presence or absence of fraudulent acts in accordance with the output from the detection means.

２）。The specific judgment algorithm of the judging means may be of various types. For example, based on the output of the vibration detecting means, the amount of vibration of the high frequency component of the vibration of the gaming machine may be determined. Is low and the amount of vibration of the low-frequency component of the vibration is large, it can be determined that there is replacement with the unauthorized product (claim 2).

できる。That is, as described in detail in the embodiment, there is a high possibility that replacement with a fraudulent product (fraud ROM) is performed while the vehicle is stopped. Since the vibration from the car is transmitted to the gaming machine during traveling, the signal detected by the vibration detecting means has a large amount of high frequency component vibration. Conversely, when the vehicle is stopped, there is no large amount of vibration of the high frequency component. In addition, when the gaming machine is lifted, the frequency is a low-frequency component. Therefore, when the vibration level of the low-frequency component is equal to or higher than a certain level, it is highly likely that the gaming machine is lifted artificially. Therefore, the vibration level of the high frequency component is low (during stop), and
When the vibration level of the low-frequency component is high (there is an artificial lift), it can be determined that there is a high possibility that the user has committed fraud.

行為をしていると判断できる。Further, as another determination algorithm, it can be determined that there is a replacement for the illegal product when the inclination angle of the gaming machine is equal to or more than a reference value based on the output of the inclination detecting means. Item 3). In other words, when the components of the gaming machine are replaced, there is a high possibility that the gaming machine is tilted as described above. Therefore, when the tilt angle of the gaming machine is equal to or greater than a certain value, it can be determined that the wrongdoing is taking place.

為ありと誤判定するおそれが可及的に抑制される。It is more preferable that the determination based on the inclination angle is performed in consideration of the determination as to whether or not the vehicle is traveling. In other words, if it is determined that there is fraud when the car is stopped and leaning, it is determined that the vehicle has been tilted artificially, for example, when moving on a sharp curve or slope, and there is fraud. The risk of erroneously determining that is incorrect is suppressed as much as possible.

It is more preferable that the acceleration sensor be capable of detecting two static accelerations. This makes it possible to combine the detection of both the inclination and the vibration into one sensor. Therefore, the number of parts can be reduced and the size can be reduced. Further, if the system is configured to detect fraud both in the inclination and in the vibration, the reliability is further improved.

に応じたアナログ電圧出力を発するようになる。FIG. 1 shows a preferred embodiment of a fraud monitoring apparatus for transporting a game machine according to the present invention. As shown in the figure, an acceleration sensor 1 is installed at a predetermined position on the back of a gaming machine such as a pachinko machine, a pachislot machine or the like. The acceleration sensor 1 is set such that the detection direction of high sensitivity is horizontal. Accordingly, the sensor output of the acceleration sensor 1 generates an analog voltage output according to the amount of vibration and / or the amount of tilt, as described later.

成分と低周波成分が分離抽出されるようになっている。The output of the acceleration sensor 1 is input to a high-pass filter 2 and a low-pass filter 6 each composed of a resistor, a capacitor, etc., so that a high-frequency component and a low-frequency component are separated and extracted. Has become.

きくなる。At the subsequent stage of the high-pass filter 2, an absolute value circuit 3 and a smoothing circuit 4 are connected in series in that order. As a result, the high-frequency component that has passed through the high-pass filter 2 passes through both circuits 3 and 4, and the amount of vibration (vibration level) of the high-frequency component is extracted. That is, the output of the smoothing circuit 4 increases as the number of high-frequency components having large amplitudes increases.

ときにはコンパレータ５の出力はＬになる。The vibration level of the high-frequency component is input to the negative side (inverting input terminal) of the comparator 5, where it is compared with the reference voltage level input to the positive side (non-inverting input terminal). Therefore, when the vibration level is equal to or higher than the reference voltage, the output of the comparator 5 becomes L.

As a result, a level corresponding to the amplitude (vibration amount or tilt amount) of the low-frequency component passed through the low-pass filter 6 is extracted. Then, the output of the smoothing circuit 8 is applied to the + side (non-inverting input terminal) of the comparator 9, where it is compared with the reference voltage level input to the-side (inverting input terminal). Therefore, when the output level of the smoothing circuit 8 is equal to or lower than the reference voltage, the output of the comparator 9 becomes L.

Accordingly, the AND circuit 10 outputs H when the vibration level of the high-frequency component is equal to or lower than the predetermined level and the level (vibration level or gradient level) of the low-frequency component is equal to or higher than the predetermined level. Then, when the output of the AND circuit 10 is H as described later, it is determined that the illegal operation has been performed.

Has a waveform as shown in FIG. Since the vibration during traveling is large and the frequency is high, the waveform that has passed through the high-pass filter 2 is as shown in FIG. And
Since the negative side is inverted in the absolute value circuit 3, the absolute value circuit 3
Is output as shown in FIG. 2C, and when the signal is smoothed by the smoothing circuit 4, a waveform having a relatively large amplitude as shown in FIG. In addition, since the amplitude level is small while the vehicle is stopped, the output level of the smoothing circuit 4 is lower than the reference level.

Is L (see e in FIG. 2). Therefore, when the output of the comparator 5 on the high frequency side is H, it can be determined that the vehicle is stopped, and when it is L, it is running.

That is, generally, when the pachinko machine is carried, the output a of the acceleration sensor 1 has a waveform as shown in FIG. As is clear from the figure, since the vibration based on the movement of a person carrying an object has a low frequency, the vibration flows only on the low frequency side, contrary to the vibration accompanying the traveling. That is, when passing through the low-pass filter 6, harmonic components superimposed on the vibration waveform are removed,

The level changes according to the inclination angle, and the sign may be reversed depending on the inclination direction. However, in any case, the tilted state does not vibrate because the frequency is 0 Hz. Then, as a matter of course, the light passes only through the low-pass filter 6.

, A waveform of an absolute amount corresponding to the tilt angle is obtained regardless of whether the output of the acceleration sensor 1 is positive or negative (see g in FIG. 4). Then, after passing through the smoothing circuit 8, a waveform like h in FIG. When the output waveform of the smoothing circuit 8 shown in FIG. 4H is equal to or higher than the reference voltage input to the minus side of the comparator 9, the output of the comparator 9 indicates H. That is, by setting the reference voltage to the output level of the smoothing circuit 8 when the pachinko machine is tilted to a certain angle or more, the output of the comparator 9 becomes H when tilted to a desired angle or more. (See i in FIG. 4).

うな所定レベルに調整しておく必要がある。It should be noted that in the present embodiment, the judgment as to whether or not the object is lifted and the judgment as to whether or not the object is inclined are both performed by one comparator 9.
Needs to be adjusted to a predetermined level so that the two states can be discriminated together.
【００３２】一方、本形態に用いる加速度センサ１の具
体的な構造としては、例えば図５に示すような重力加速
度等の静的加速度（周波数０Ｈｚの加速度）の検出が可
能な、静電容量型加速度センサを用いることができる。

この重り１ｄに加速度や振動などの物理量が加わると、
その方向に重り１ｄが変位する（梁部が撓む）。On the other hand, as a specific structure of the acceleration sensor 1 used in the present embodiment, for example, a capacitance type acceleration sensor capable of detecting a static acceleration (acceleration at a frequency of 0 Hz) such as a gravitational acceleration as shown in FIG. An acceleration sensor can be used.
As is well known, this acceleration sensor is integrated by interposing a semiconductor substrate 1c such as silicon between two fixed substrates 1a and 1b made of, for example, a glass substrate. Then, the semiconductor substrate 1c integrally forms a weight 1d that is cantilevered by a beam portion with respect to a surrounding frame. Therefore,
When a physical quantity such as acceleration or vibration is added to this weight 1d,
The weight 1d is displaced in that direction (the beam portion bends).

極１ｅ，１ｆに所定の出力回路を組み込むことにより、
物理量（重りの変位量）に応じた電圧がセンサ出力とし
て出力するようにしている。A fixed electrode 1e is formed by evaporating aluminum or the like on the surface of one fixed substrate 1a facing the weight 1d, and the weight 1 facing the fixed electrode 1e.
The opposing surface of d becomes the movable electrode 1f, and a capacitance corresponding to the distance between the electrodes is generated between the two electrodes 1e and 1f. Therefore, when the weight 1d is displaced as described above, the capacitance also changes.
That is, a variable capacitor is formed. Therefore, the amount of displacement of the weight 1d and thus the added physical amount can be detected from the change in the capacitance. In this embodiment, a predetermined output circuit is incorporated in both electrodes 1e and 1f,
A voltage corresponding to a physical quantity (a displacement amount of the weight) is output as a sensor output.

る。That is, as shown in FIG. 5, when acceleration (the direction of the arrow in the figure) is applied in the left-right direction, the movable electrode 1f shared with the weight 1d moves in the left-right direction.
The capacitance of the capacitor composed of f changes, and the acceleration can be measured by detecting the change. The vibration is that acceleration is repeatedly applied alternately in the left-right direction.

Is inclined, the weight inclines to the left and right due to the gravitational acceleration (in the direction of the arrow in the figure), and the distance between the electrodes changes (the width in the figure (A) becomes narrower, and the figure in (B) becomes wider). The amount of tilt can also be measured.
【００３６】このように、本加速度センサを用いること

とができる。As described above, by using the present acceleration sensor, the vibration amount and the inclination amount can be measured by one sensor, so that the cost can be reduced due to the common use of components.

チンコ台が人為的に持ち上げられたり、傾けられたとき
に不正行為が行われたと判断するようにしている。Next, an operation of the above-described monitoring device, that is, an example of a fraudulent judging method will be described. Generally, fraudulent acts such as exchange of fraudulent ROM during transportation are performed when the vehicle is stopped. Therefore, when the car is stopped and the pachinko machine is artificially lifted or tilted, it is determined that the wrongdoing has been performed.

Ｌとなる。従って、低域側のコンパレータ９の出力に関
係なくＡＮＤ回路１０の出力もＬとなり、不正行為は行
われていないと判断する。That is, when the car on which the pachinko machine is mounted is running, the output of the comparator 5 becomes L since the vibration amount of the high frequency component is equal to or higher than the predetermined level as shown in FIG. Accordingly, the output of the AND circuit 10 also becomes L irrespective of the output of the comparator 9 on the low frequency side, and it is determined that no illegal action has been performed.
【００３９】次に、パチンコ台が人為的に持ち上げられ
たり、傾けられたりしていないときには、図３，図４に

る。従って、高域側のコンパレータ５の出力、つまり、
走行中か停車中かに関係なくＡＮＤ回路１０の出力もＬ
となり、不正行為は行われていないと判断する。Next, when the pachinko machine is not lifted or tilted artificially, as shown in FIGS. 3 and 4, the amount of vibration or tilt of the low frequency component is below a predetermined level. Therefore, the output of the comparator 9 becomes L. Therefore, the output of the comparator 5 on the high frequency side, that is,
The output of the AND circuit 10 is also low regardless of whether the vehicle is running or stopped.
It is determined that no wrongdoing has been performed.
【００４０】そして、停車中で、しかも、パチンコ台が

れたと判断する。そして、ＡＮＤ回路１０の出力がＨの
ときの時刻が、記憶部１２に格納される。When the vehicle is stopped and the pachinko machine is lifted or tilted artificially, the outputs of the comparators 5 and 9 both become H, so that the output of the AND circuit 10 becomes H. Judge that wrongdoing has been committed. Then, the time when the output of the AND circuit 10 is H is stored in the storage unit 12.

くしなくてすむ。As described above, if the car is stopped and the pachinko machine is lifted or tilted artificially, it can be determined that there has been fraud, and the determination is made based on the output of the acceleration sensor. Since it can be performed simply by performing predetermined signal processing, the circuit is simple and the circuit scale does not need to be so large.

る。When a pachinko machine arrives at a delivery destination and is transported and delivered to a pachinko parlor, the pachinko machine is manually lifted or inclined while the car is stopped. Therefore, it is necessary to distinguish such a normal act from an illegal act of exchanging an unauthorized ROM. Therefore, in this embodiment, the time data at the time of judging fraud is also stored, so if the time of judging fraud is in transit, it is determined to be fraudulent and arrives at the pachinko parlor. If you are carrying in,
It can be judged that it is not fraudulent because of the carry-in. This makes it possible to reliably recognize the presence or absence of fraud.

Furthermore, the output of the AND circuit 10 may be connected to an alarm device, and an alarm may be sounded when it is determined that an illegal act has occurred. By sounding the alarm in this way, not only can fraudulent acts be prevented, but also a person who has attempted fraudulent acts can be suppressed. Also, in the case of regular carry-in, there is no problem even if an alarm sounds, since it is clear that it is not a fraud. Of course, it is annoying that the alarm keeps sounding when carrying in, so it is of course better to install a switch to stop the alarm.

Although it is determined by one comparator 9 to determine whether or not the user has lifted and whether or not the user has tilted, each of them may be determined by another system. This allows the reference voltage to be set according to each state,
It is possible to make a more accurate determination.

It is possible to judge whether or not a wrongdoing has been done to replace it with a fraudulent product. In particular, when configured as in claim 2, the abnormality determination is not performed when a large vibration is applied, such as when the vehicle is running, so that the possibility of erroneous determination is suppressed as much as possible. Further, according to the structure of the fourth aspect, since both inclination and vibration can be detected by one sensor, the number of parts can be reduced and the size can be reduced.
