The game machine 1 is equipped with a probability generator 2 for generating a hit probability (event) together with a game machine circuit 3 for controlling the hit / off operation of the game machine. Are connected to various sensors 4 including a winning sensor disposed at a predetermined location in the machine.

Determine hit / miss from the HIT signal from circuit 3, and
A basic probability generation function that generates a hit signal with a constant probability
In addition to the probability generation circuit 6 provided, a memory circuit 7, an abnormality detection circuit 8, a monitoring data generation circuit 9, and an optical communication circuit 10 described below are provided. It is configured to realize a monitoring system. The random pulse generator 5, the probability generation circuit 6, the optical communication circuit 10 and the like are housed in an integral shielded housing that is difficult to open.

Here, the abnormality detection circuit 8 is a circuit for detecting an illegal act or an operation abnormality in the probability generating device 2, for example, detecting an abnormal number of consecutive hits (an abnormal number of consecutive hits is a predetermined error) Detection of power supply voltage abnormalities, detection of electrical spike noise, detection of fluctuations in electrical delay time due to opening of the shield housing, also by opening the housing Various detections shown in FIGS. 2 and 3, such as detection of inflow of light into a housing, detection of disconnection or short circuit on a specific circuit, detection of unauthorized replacement of a hit signal on an output terminal for connection with a game machine circuit 3, etc. A detection mechanism is provided.

The memory 7 circuit includes individual identification information for individually specifying the probability generator 2, current operation information, probability generation reference table information set for generating a base probability, random pulse information, The basic operation information is stored, and the monitoring data generation circuit 9 collects the abnormality detection information, individual identification information, basic operation information, etc. together with the hit signal generated by the probability generation circuit 6 as shown in FIG. It laid out a series of monitoring data. This monitoring data is transmitted outside the apparatus from a communication mechanism in which electrical fraud is unlikely to occur, for example, when an infrared ray is used as a medium, an optical communication circuit 10 including an infrared transmission unit.

In the above configuration, the winning signal output from the probability generating circuit 6 is used for controlling the hitting operation of the game machine circuit 3, and the management computer 2 through the transmission line A.
1 is transmitted. At the same time, the monitoring data transmitted from the optical communication circuit 10 is converted into an electrical signal by the optical receiver 11 outside the apparatus, and transmitted to the management computer 21 via the transmission path B.

The management computer 21 receives the hit signal from the game machine circuit 3 transmitted via the transmission line A and the transmission line B.
Is compared with a hit signal in the monitoring data transmitted from the optical receiver 11 via the receiver, and if the hit / miss does not match, it is determined that an illegal act has been made in the probability generator 2 An alarm is issued from the device 22.

In the present invention, the contents of fraud or abnormality can be instantly specified by the abnormality detection information laid out in the monitoring data. Similarly, it is also possible to monitor fraud and abnormalities based on differences from individual identification information registered on the monitoring side, differences in base setting information, and transitions from the start of the current operating status. .

FIG. 6 is a flowchart showing an abnormality determination process based on the individual identification information.
1, the individual identification information of the probability generator 2 is registered, and this and the probability generator 2 laid out in the monitoring data

Further, the probability generation reference table of FIG. 4 is probability generation reference information obtained by constantly statistically calculating the average number of pulses per unit time of the random pulse generator as an exponential function table during operation. If the number of random pulses is manipulated due to an abnormality or the table value itself is altered, it will be out of the specified exponent curve. Accordingly, it is possible to determine whether the probability is appropriate or not by monitoring this probability generation reference table. [Example]

Next, an embodiment of the game machine monitoring system according to the present invention constructed in the game hall will be described with reference to FIG. Note that a plurality of game machines are arranged in the game hall for each model, and this model-specific block is called a sima. In this figure, one of the game machines constituting this strip is shown.

As shown in FIG. 5, the probability generator 2 of the present invention is incorporated on the main board on the back of the game machine 1 main body. As described above, the HIT signal generated by the winning sensor (4) or the like of the game machine 1 is input to the probability generating device 2 to determine hit / miss, and the information is passed to the main board as a game machine operation signal. The game machine circuit (3) in the main board controls the hit / miss of the game machine, and the game machine operation signal that has passed through the game machine circuit is installed in a separate room via the existing transmission line A. It is transmitted to the management computer (21). Here, when the game machine operation signal of the game machine circuit is tampered with, the information is different from the information generated by the probability generator 2.

In this embodiment, in order to reliably receive the monitoring data transmitted from the optical communication circuit (10) in the probability generator 2, the optical receiver 11 is installed in the vicinity of the infrared transmitter. . In addition, since a large number of game machines 1 are arranged in the Shima, in order to prevent mutual interference with infrared signals emitted from other adjacent game machines 1 and unauthorized intervention or interference with infrared communication, Appropriate considerations have been made in various points such as communication distance, installation interval, directivity of transmitted / received light, transmission power, and installation of a light shielding hood cover.

The monitoring data from the receiving unit 11 is collected by the concentrator 12 together with the monitoring data of the other game machines 1 in the stripe, and sent to the management computer through the existing or dedicated network B. In addition, monitoring data from other stripes is also connected to the same network, and the monitoring data is sequentially transmitted to the management computer in the same manner. In addition, in the communication in the hall, it is also possible to perform infrared communication in a unique format using the infrared transmission unit 13 installed in the strip without using a cable (in this case, the information transmission path is shown in FIG. 5). It becomes a transmission line C indicated by a broken line).

The details of the subsequent abnormality monitoring by the management computer are as described above. In addition, by providing an alarm display function for detecting fraud and abnormality on the probability generator 2 side, if this monitoring system stops due to a problem, the alarm display of the probability generator 2 can be used without using the monitoring system. It is possible to confirm fraud and abnormalities by visual inspection.
