In this way, influence of electrostatic noise can be lowered, and radio wave hindrance can be absorbed by a loop structure of the middle plate 57, and consequently, a comfortable game parlor management can be carried out.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to noise prevention in a ball game machine.

[0002]

2. Description of the Related Art Conventionally, a pachinko machine and an arrangement ball game machine typified by a ball game machine are used as places where the game balls come into contact, especially from a prize ball tank, a lower plate discharge port (also called a bucket) and a payout device. A metal plate is applied to the hitting surface of the paid game ball or the like, and is connected to the ground (symbol name GND) of the game control device via an electronic component. Regarding the connection of the prize ball tank, a series resistor is inserted to prevent sparks from generating sparks.

[0003]

However, there are many sliding surfaces of the game ball on the mechanism board, and static electricity of a very high voltage is generated especially on the surface that is impacted. The mechanism board made of plastic has almost no conductivity, and if impact continues, static electricity is accumulated and collected on metal parts such as screws to be assembled, and eventually discharged to any conductive material. In this case, since the accumulated static electricity has little current-like energy and voltage-like energy, the generated spark cannot be observed. However, the electromagnetic waves accompanying this enter the data bus, the address bus, and the control control line of the game control base mainly composed of the CPU and the pattern control base, and are treated as different data, causing a runaway phenomenon or abnormal operation. It often occurs during the dry period of air from mid-October to mid-April of the year, especially during the period from mid-February to mid-March, the humidity level in pachinko parlors is below 30%, and the operating status of gaming machines is the worst. Will be.

As a countermeasure against this, in addition to the method described in the prior art, a method of mixing a conductive substance with plastic is taken, but after all, the disadvantage that the substance becomes soft due to the incompatibility of the substance and the connectivity between the conductive substances is small. It has the drawback that it deteriorates over time and its effect decreases. In an experiment conducted by the inventor, the antistatic agent of trade name "Elegard" was sprayed, but the effect was lost in about one week, and the antistatic agent deteriorated and became more dielectric. As a further measure, the board designer has taken measures to increase the dielectric effect by increasing the area of the + side of the board and the ground part. Since the harness wire to be connected is also an antenna, it will be absorbed by all the lines and data will be taken in by the resonance phenomenon due to the dielectric and the wiring pattern and abnormal operation will occur, and the software designer will take measures on software. I take it, but I could not deal with the phenomenon of rewriting data.
However, unless the source of generation was suppressed, the above-mentioned measures would be overtaken, and it was difficult to suppress it. Conventionally, the front frame is made of wood and is slightly conductive, so it is discharged to the screw that fixes the middle plate, and the front frame that conducts electricity has resistance, so electromagnetic waves are not generated and it is not seen as a problem. With the advent of plastic front frames, the plastic front frame must maintain its strength, and depending on the material, static electricity may be generated due to convection of air. The reality is that the electrode properties are different and the situation is serious.

[0005]

A ball game machine according to claim 1 is supported by the front frame through an outer frame, a front frame pivotally supported by the outer frame, and a game board frame. In a ball-and-ball game machine including a gaming board, a payout device for paying out prize balls according to winning, and an upper plate that receives the prize balls paid out from the payout device, the gaming board frame is It is characterized in that the upper prize ball contact portion provided on the game board frame is electrically conductive.

Since various metallic parts are attached to the game board frame, the contact between the plastic and the game ball or the static electricity naturally generated can be collected in the game board frame which becomes the common ground and is formed on the frame. Therefore, since the loop and the natural capacity also serve as a low-pass filter, all the artificial or non-artificial noise, for example, static electricity and radio waves of a mobile phone can be removed.

According to another aspect of the ball game machine of the present invention, an outer frame, a front frame pivotally supported by the outer frame, a game board supported by the front frame via a game board frame, and a hinge for the game. In a ball game machine provided with a mechanism board that is openably and closably attached to a board frame, the ground terminal that is electrically connected to the game board frame when the mechanism board is closed with respect to the game board frame is the mechanism. By providing the external connection terminal board provided on the board,
Since the ground terminal is connected to the ground wire of the game machine installation island by an electric wire so that static electricity can be discharged to the outside from the ground terminal, the static electricity of the ball game machine can be released to the game machine installation island.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As for the common earth, for example, in the case where a plastic front frame and a middle plate are integrally formed, it is not necessary to plate the whole, and unnecessary parts are plated (game). There is a problem in terms of cost and inconvenience because it is inconvenient for the customer.
In this case, a method of wrapping a copper wire around the portion belonging to the middle plate may be considered, and a plurality of low-pass filters having different thicknesses may be bundled to form a low-pass filter having a plurality of frequencies.
There is also a method in which a conductive plate is attached to the portion that will become the middle plate. Next, the embodiments of the present invention described above will be specifically described with reference to the examples of the present invention.
