[0007]

By the way, the pachinko balls as the above-mentioned game media are used when the pachinko balls are rubbed against each other when the pachinko balls are washed or polished by a polishing device or when they are moved in the ball replenishing equipment. Rubbing with equipment makes it easier to charge static electricity. For this reason, in the above-described pachinko gaming machine P, since the pachinko balls charged with static electricity are often supplied from the ball supply equipment to the ball storage / discharge path section 91, the external static electricity is grounded to take measures against noise. Many technical proposals have been made. On the other hand, even when the replenished pachinko balls move in the pachinko gaming machine P, static electricity may be generated due to the contact between the pachinko balls and each of the constituent members, so that the internal static electricity generated in the gaming machine may be generated. In the same manner, a technical proposal has been made in which grounding is taken to prevent noise.

However, a new type of pachinko gaming machine P designed and manufactured in recent years is very easily charged because the use ratio of synthetic resin molded parts is further increased and the number of sources of static electricity is also increased. Therefore, in various grounding modes proposed so far, it is impossible to reliably ground all static electricity and take measures against noise. Therefore, in the pachinko gaming machine P manufactured in recent years, noise generated due to static electricity causes
Each of the devices 122,1 for controlling components of the gaming machine P
23, 126, 127 substrates and various substrates 121, 124, 1
There is an increasing number of cases in which malfunctions or failures occur due to the influence of such as 25, and establishment of an appropriate noise countermeasure technology by reliably removing static electricity from the ground is desired.

[0009]
