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 ball is washed or polished by a polishing device or when the ball is moved in the ball supply facility. Rubbing with equipment makes it easier to charge static electricity. For this reason, pachinko balls charged with static electricity are often supplied from the ball replenishing equipment, and in the above-mentioned pachinko gaming machine P, the static electricity that enters from the outside through the pachinko balls (hereinafter referred to as “external static electricity”) is appropriately reduced. It is necessary to take sufficient countermeasures against static electricity by discharging and removing. On the other hand, even when the replenished pachinko balls move in the pachinko gaming machine P, static electricity may be generated due to contact between the pachinko balls or contact with each of the constituent members. It is necessary to properly discharge and remove the generated static electricity (hereinafter referred to as “internal static electricity”) and take sufficient measures against static electricity.

Here, for example, in the gaming board I, since various electric parts equipped with detection switches such as a winning opening and a winning device are mounted, erroneous operation of the detection switches (erroneous detection, (Not detected), etc., and disadvantageously giving a disadvantage to the player or the game hall occurs. Therefore, as a countermeasure against static electricity for the game board I,

When set to 2, the holding frame 22 and the metal member come into contact with each other to establish electrical continuity therebetween, so that static electricity charged on the game board I is discharged to the ground via the holding frame 22 and the like. Measures have been proposed.

However, in the above-described countermeasures against static electricity of the game board, static electricity is discharged to the ground via the constituent members of the pachinko gaming machine P including the holding frame 22. For this reason, if the potential of the static electricity charged on each of the constituent members is higher than the potential of the static electricity charged on the game board I, the static electricity charged on the constituent members flows backward to the game board I, and the game board I The problem inherently arises that the amount of electrostatic charge I increases rather. Also,
When the installation state of the game board I with respect to the holding frame 22 is inappropriate, the electrical conduction between the holding frame 22 and the game board I due to the metal member and the holding frame 22 not being securely contacted. There has been a problem that static electricity generated in the game board I cannot be discharged properly and reliably.

As described above, in the pachinko gaming machine P of the present embodiment, the middle frame B, the front frame C, the upper bowl D,
Component members such as a lower ball tray E, a game board I, a mechanism set board H,
The various attached members and parts provided in these constituent members B, C, D, E, I, H are made of a synthetic resin material containing a conductive agent and / or
Or molding from synthetic resin material containing antistatic agent,

Simply connecting the second connector 143 provided on the tenth ground line 160 to the second ground connector 141 of the power supply board 131 ensures reliable electrical continuity between the game board I and the power supply board 131. Thus, for example, regardless of the installation state of the game board I with respect to the setting port 23 of the holding frame 22, the discharge of static electricity can always be reliably and appropriately removed. As a result, malfunctions (erroneous detection, undetected) of the detection switch due to charging of the game board I with static electricity, and the like are prevented. Furthermore, when removing the game board I from the holding frame 22, the second
Only by pulling out the connector 143 from the second ground connector 141, the game board I can be detached.
When the game board I is mounted, the countermeasure against static electricity of the game board I is achieved only by inserting and connecting the second connector 143 to the second ground connector 141, which hinders the attaching / detaching work of the game board I. Nothing.

Although not specifically mentioned in the above embodiment, each component that the game ball directly contacts, such as a start winning hole for a symbol display device, a lamp lens of an illumination member, and the like, is also subjected to metal plating. Is performed to achieve electrical continuity with the carbon paper 77, the efficiency of removing static electricity generated and charged in the game board I can be further increased.

As described above, in the game board of the pachinko game machine according to the present invention, the static electricity charged on the game board components, the decorative members plated with metal, etc. is transferred to the back of the plywood via the sheet-like conductive material. After flowing to the conductive member arranged on the side,
It is discharged directly to the power supply substrate. That is, since direct electrical conduction between the game board and the power supply board is achieved, even if the potential of the static electricity charged on the other components of the game machine is higher than the potential of the static electricity charged on the game board, This has the beneficial effect that the inconvenience that the static electricity of the constituent members flows backward to the game board is avoided, and the malfunction of the detection switch due to the static electricity is preferably avoided. Note that the conductive member and the sheet-shaped conductive material may adopt a form in which electrical conduction is provided by a ground wire connected to the decorative member, or a form in which electrical conduction is provided by an attachment member for attaching the conductive member to plywood, and the like. In any case, the sheet-shaped conductive material and the conductive member are appropriately conducted. Also, proper electrical continuity between the conductive member and the power supply board can be ensured only by properly inserting and connecting the connector of the ground wire connected to the conductive member to the connector receiving portion provided on the power supply board. Discharge of the static electricity. Furthermore, when removing the game board, the removal of the game board is permitted only by pulling out the connector from the connector receiving portion of the power supply board, and when mounting the game board, the connector is inserted and connected to the connector receiving section of the power supply board. Since the countermeasures against static electricity of the game board can be achieved only by itself, there is an advantage that the work of attaching and detaching the game board is not hindered. In addition, since there is no need to perform any pull-out work or plug-in work related to connectors other than the connector at the time of attaching / detaching the game board, there is also an advantage that the electrical system is appropriately maintained in the state at the time of factory shipment.
