JP3690727B2 - Pachinko gaming machine with ball stop prevention structure - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine having a ball stop prevention structure that prevents ball stop (ball biting) of a game ball.
[0002]
[Prior art]
Conventionally, a set board arranged on the back of a game board of a pachinko machine is fixed to the game board (plywood board) with a wood screw, and guides a game ball (hereinafter referred to as a winning ball) that has won a prize from a prize winning opening. A proximity switch that counts the winning balls is attached to this cage.
[0003]
In general, the set plate is a so-called resin molded product made of ABS (acrylonitrile / butadiene / styrene copolymer) resin or PC (polycarbonate). There are variations in quality.
[0004]
Then, the set board may float from the back surface of the game board due to the looseness of the wood screws, the warp or the like.
[0005]
[Problems to be solved by the invention]
As mentioned above, when the set board floats from the back of the game board, the winning ball will stop at the proximity switch (also called ball biting). There was a problem that the number of wood screws increased by that amount.
[0006]
In addition, the above-mentioned ball stop has a problem that leads to interruption of the game and fraud.
[0007]
The present invention has been made to solve the above-described problems, and an object thereof is to prevent the set board from floating without increasing the number of wood screws and without increasing the number of work steps.
[0008]
It is a further object of the present invention to prevent game interruptions and cheating due to ball stopping.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention of the pachinko gaming machine according to claim 1 includes a set board as a winning ball guiding member disposed on the back surface of the gaming board of the pachinko gaming machine, and a circuit mounting member that covers the set board. The proximity switch incorporated in the set plate is structured to press the lower part of the set plate where the circuit mounting member is pressed down, and the proximity switch is formed on the set plate to guide the winning ball It is attached .
[0010]
Here, a flange is provided in the lower portion of the set plate so as to extend around the outside, and the flange is pressed against the back surface of the game board by the circuit mounting member .
[0011]
Further, at least two of the flanges may be provided.
[0012]
In addition, the circuit attachment member may include a pressing portion that presses the lower portion of the set board from above when assembled on the back surface of the game board by a fixture.
[0013]

By inserting the proximity switch floating prevention portion 208 into the notch portion of the set plate holding portion 209 and pressing the proximity switch floating preventing portion 208 by the set plate holding portion 209, the floating of the set plate 201 is eliminated.
[0038]
(Other embodiments)
In the above-described embodiment of the present invention, the proximity switch floating prevention portion is pressed by the set plate pressing portion of the assembly rod of the circuit adapter set. However, the present invention is not limited to this, for example, an upper cover that covers the set plate Similarly, it is possible to prevent the set plate from being lifted by using the accessory protection cover.
[0039]
【The invention's effect】
As described above, according to the present invention, since the lower part of the set board having the winning ball guiding path where the proximity switches are concentrated is pressed by the circuit mounting member ( circuit adapter ) , the number of wood screws is reduced. This can be reduced, and without increasing the number of work steps, the set plate can be prevented from floating, and the ball stop (ball engagement) of the proximity switch portion can be prevented.
[0040]
Further, according to the present invention, since the set plate extension is not stopped by the wood screw, the number of man-hours can be reduced.
