Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to an antistatic mechanism for a ball game machine that removes the charged charge of the game ball.
[0002]
[Prior art]
A conventional ball game machine, for example, a pachinko game machine, is provided with a game board having a game area formed on the front side thereof, and a game ball fired from a launch device in response to a player's launch operation is released from the game board. The game is guided to an outer guide rail and an inner guide rail standing upright in a substantially circular shape from the apparatus and is launched into the game area. However, in this kind of game ball, it often passes through many guide rods and collective plates in the mechanism board of the pachinko game machine, and is often charged by contact friction with these.
[0003]
This charged game ball comes into contact with a game ball guiding member such as a nail provided in the game area and generates electrostatic induction noise due to a discharge phenomenon, which needs to be prevented. Conventionally, a launching ball backflow prevention piece (for example, a later-described figure) made of an elastic thin plate-like metal member provided in the inner guide rail in the launching ball guiding path formed between the outer guide rail and the inner guide rail. 3 (see reference numeral 87 in FIG. 3) and a game ball, and a convex metal piece provided on a frame plate portion such as a glass frame member that is attached to the front side of the pachinko gaming machine so as to be openable and closable and fixes glass or the like. Is brought into contact with the inner guide rail and grounded (grounded) via a grounding member such as a grounding wire provided in advance in the game facility through the metal piece of the glass frame member.
[0004]
However, when a metal piece is provided on a frame plate portion such as a glass frame member that can be freely opened and closed as described above, and this is brought into contact with the inner guide rail, the metal piece such as a glass frame member is used. Because of the requirement for reliable contact with the inner guide rail, it is necessary to perform the attachment a little tightly. For this reason, there is a problem that it becomes difficult to open and close because of a large resistance when the glass frame member is opened and closed. In addition, the glass frame member on the front side of this type of gaming machine is frequently opened and closed for game board repairs, maintenance inspections, etc., so that the metal piece attached to it has metal fatigue, wear and deformation. In such a case, the contact between the metal piece and the inner guide rail becomes incomplete or impossible, and the charge removal of the game ball cannot be performed effectively. There was a problem.
[0005]
[Problems to be solved by the invention]
The present invention has been proposed in view of such circumstances, and proposes an antistatic mechanism for a ball game machine that is not affected by the opening and closing of the glass frame member and more effectively removes the charged charge of the game ball. Therefore, it is an object to suppress electrostatic induction noise caused by a discharge phenomenon of a charged game ball.
