Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pachinko game machine in which a wooden frame is provided with an upright board having a ball supply passage made of synthetic resin and an electronic control circuit on the back side.

Conventionally, in this type of pachinko game machine, when the pachinko balls fall along the ball replenishment path provided on the back of the upright board and fall into the saucer provided at the bottom of the upright board, the pachinko balls become electrically charged (especially when they fall). When the ball hits the synthetic resin ball supply path and becomes charged), this charge generates a spark, which enters the nozzle and enters the electronic control circuit that adjusts the enlargement of the socket for the hit ball, potentially causing the circuit to malfunction. . In addition, if the room in which this pachinko machine is installed is dry, static electricity is likely to be generated, and the balls will become charged and dirt will easily adhere to them.Moreover, in dry conditions, the balls tend to flow and the amount of ball flow increases. Furthermore, there was a risk that dust or the like would adhere to the balls due to electricity.

The present invention was devised in view of the above circumstances, and its basic configuration is to place a conductive discharge plate on the upper tray of the supply passage, and to place a conductive discharge plate between the discharge plate and the wooden frame. , is characterized by being provided with a conducting wire. That is, in the present invention, a wooden frame containing moisture and a low electrical resistance value is used as a ground, and the balls that are charged when they hit the ball supply path are discharged to the wooden frame via a discharge plate and a conductive wire. This excludes defects in conventional products.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, a is a wooden wooden frame made of plywood or the like, b is an upright plate that is removably attached to this wooden frame a, and what is shown is the back side of the upright board b. On its surface are nails, hit ball sockets,
A ball dropout port is provided, and a ball supply section 3 is provided at the top of the back side as shown in the figure, and from this ball supply section 3, the balls are sent to the upper tray of the ball supply passage A made of synthetic resin. 4 (Fig. 2). The balls 10 that have fallen into the upper tray section 4 pass through a zigzag-shaped ball supply passage I (not shown) to the lowermost tray section 5.
The balls then fall into the receiving tray 6 below the receiving tray portion 5 (FIG. 3), and an electronic control circuit (b) is disposed near the ball supply passage (a).

Places that are easily charged in the above conventional product, for example, the upper tray portion 4 and the lower tray portion 5 in the ball supply passage A where the balls 10, 10, etc. fall and become charged.
, conductive discharge plates 1, 1' are provided, and conductive wires 2, 2' are connected to the discharge plates 1, 1' and the wooden frame a, so that the charge on the ball 10 is transferred to the discharge plates 1, 1', 1', Conductor 2,
2' to the wooden frame a.

The discharge plate shown at 1 is provided in a U-shape along the upper tray portion 4 (FIG. 4), and the discharge plate shown at 1' is formed into a cylindrical shape (FIG. 5). In other words, 10 balls,
10...The shape and the like are not limited to those shown in the drawings as long as they come into contact. The conductive wires 2, 2' are inserted into metal fittings provided on the wooden frame a so that they can be removed from the wooden frame a.

In this way, in the conventional product, for example, the upper tray portion 4 of the ball supply passage A is charged with a voltage of 10KV to 15KV, but in the present product, as described above, the discharge plates 1, 1', the conductor 2,
2' to the wooden frame a, and the conductors 10, 10
...is not charged like conventional products.

According to the present invention, as described above, the balls are charged by falling into the upper tray of the ball supply passage, but as described above, the balls are discharged to the wooden frame via the discharge plate and the conducting wire. Therefore,
Not only does it prevent malfunctions and breakdowns in electronic control circuits caused by sparks generated as the balls become electrified, but it also makes cleaning the balls easier and saves labor because dirt and dust cannot be absorbed by the balls. can be achieved.
