Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing static electricity generated by friction between a pachinko ball and a pachinko ball path, in a pachinko machine. 2. Description of the Related Art While a pachinko ball discharged from a ball tank or punched from an upper plate passes through various pachinko ball passages such as a synthetic resin prize ball passage, a safe ball passage, and an out ball passage,
A voltage of about 13000 V is generated in the pachinko ball due to friction with the passage. For this reason, the patron's hand trying to take out the pachinko balls accumulated in the ball dish becomes numb, or the noise caused by the electric charge on the pachinko balls affects the control board of the pachinko machine. Gaming machines in which a conductive member for removing static electricity charged in a pachinko machine is provided in a pachinko ball path are known, for example, from JP-A-61-29377 and JP-A-60-13174. The gaming machine described in JP-A-61-29377,

In this way, the conductive member 33 and the conductor 21 are electrically connected. Further, the conductive member 33 may be provided along the entire length of the pachinko ball passage 24, but it is sufficient to provide one conductive member in each passage. Next, an embodiment of a device for removing static electricity will be described with the ball tank 25 as an example. FIG. 7 is a block diagram of the control board 43 of the pachinko machine 1. The control board 43 has a CPU, ROM, RAM, switch detector,
It has a clock circuit, reset circuit, power supply, LED display circuit, motor control unit, two solenoid drive units, three lamp drive units, audio drive unit, and analog ground. The switch detection unit starts the first kind through channel CN6. The mouth detecting switch 1, the first-type starting opening detecting switch 3, the accessory continuous operation detecting switch and the special winning opening winning detecting switch are communicated to the left ascending and descending operation detecting switch via the channel CN7. In addition, the LED display circuit communicates with the left, middle, and right symbol indicators, the stored number indicator, the continuous count indicator, the large winning award winning indicator, and the decorative LED via channels CN4 and CN5. The dispensing motor and the firing motor are communicated via the channel CN7, and the two solenoid driving units are respectively driven via the channel 7 by the right lifting plate driving solenoid,
The winning opening opening solenoid is communicated via channel CN3. In addition, each of the three lamp drivers has a channel CN
The indicator light A, the indicator light B and the indicator light C are communicated via 3 and the audio drive unit communicates with the speaker via channel 8;
The power supply is connected to the power supply 24V AC through channel 2. If the potential of the control board ground 38 and the electric potential of the pachinko ball path 24 are equal, the control board 43 will not be affected by noise due to static electricity. Therefore, as shown in FIG. 7, the analog ground 38 of the control board 43 is connected to the conductive member 33 provided in the pachinko ball path of the pachinko machine 1. This is, as shown in FIG. 8, the contact surface of the ball tank 25 with the pachinko ball,
For example, it is preferable that the conductive member 33 be fixed to the inner surface 39 of the side wall with a double-sided tape 40, and the conductive member 33 and the ground 38 of the control board 43 be electrically connected via the resistor 41. Whether the screw 36 or the double-sided tape is used to attach the conductive member 33 is interchangeable, and can be appropriately selected depending on the attachment location and the like. According to the static electricity removing device by the pachinko machine of the present invention,
By operating the opening / closing lid and opening the ball hole, the pachinko balls can be discharged without touching the pachinko balls accumulated in the ball receiving recess of the ball tray, and the ball can be ejected without opening / closing the opening / closing lid. Since the static electricity charged in the pachinko balls stored in the saucer is discharged by being discharged to the ground through the opening / closing lid and the conductive wire made of a conductive material, it is possible to eliminate discomfort caused by contact with the pachinko balls. Since the opening / closing lid also serves as a conductive material, there is no need to separately provide a conductive member for removing static electricity in a ball tray made of synthetic resin.
