Description

TECHNICAL FIELD The present invention relates to a ball game machine such as a pachinko machine, and in particular,
The present invention relates to a ball game machine equipped with a device for electrically controlling electric components used in a ball game.

[Prior Art] In a pachinko machine and other ball game machines, various electric components mounted on the game board are electrically connected to a control device composed of electronic circuits and a power source. Wiring exists. For example, in a pachinko machine, in order to control the opening and closing of a variable winning ball device typified by an electric tulip and the lighting of various lamps, wiring that connects these electrical components to the CPU and power supply, signals that send signals from various sensors to the CPU Lines are lined up.

In such a ball game machine, collision frequently occurs between game balls represented by pachinko balls or between the game ball and the ball passage wall surface during the game, but at that time, static electricity is generated and the game ball is generated. Is charged. If the number of game balls is large, the electrostatic voltage will be 10,000 V or more, and if it exceeds the charge capacity of the game balls, it will be discharged to the surrounding conductors. If this discharge occurs to an electronic control device such as a CPU or its input / output line, the control device may malfunction due to the influence.

Therefore, as shown in JP-A-61-29377 and JP-A-64-80384, a conductive member is provided in the passage of the pachinko ball,
There is known a pachinko gaming machine in which static electricity is released by connecting a conductive wire to the conductive member.

[Problems to be Solved by the Invention] However, in the structure for removing static electricity as described above, there is a problem that the number of parts is increased and it is time-consuming to mount a conductive member or connect a conductive wire to the sphere current supply. .

In addition, a ball passage is formed on the back side of the game board,
Since there are many wirings connected to the above-mentioned electrical components, if a conductive member is attached to the ball passage and the conductors are connected as described above,
There is also a problem that the limited space on the back side of the game board is further limited, and the wiring process becomes more complicated.

Therefore, an object of the present invention is not a conventional method of mounting a conductive member in a ball passage and connecting conductors, and there is no problem of wiring processing on the back side of the game board, and a ball-ball game machine which is less likely to be adversely affected by static electricity. Is to provide.

[Means for Solving the Problems] The present invention provides a ball equipped with a device for controlling a ball path plate having a ball path on the back surface on the back side of a game board and for controlling an electric component used in a ball game. In a ball game machine, a game board and a ball passage plate are formed of an electrical insulator, and a wiring board for electrically connecting the above-mentioned electrical equipment to a control device is arranged between the game board and the surface of the ball passage plate. It is characterized by having done.

The wiring board is preferably formed of a flexible sheet having a large number of conductors arranged on the surface, and in that case, a conductive portion for electrically connecting the electric component to the control device is provided at a predetermined position on the surface of the flexible sheet. It is arranged and the conductor part is connected to this.

[Operation] In the ball game machine of the present invention, the wiring board connected to the electrical equipment is sandwiched between the board and the surface of the ball passage plate on the back side of the game board formed of an electrical insulator. Covered. Therefore, even if the game ball that moves from the board surface of the game board to the back side and passes through the ball passage on the back surface of the ball passage plate is charged and reaches a predetermined voltage, the wiring board is protected from discharge and the influence of static electricity is reduced. It is possible to minimize the influence on the electronic control device such as the CPU.

When the wiring board is formed of a flexible sheet,
You can put the electrical equipment in the mounting hole provided in the game board and make the conductive part of the flexible sheet contact the contact part of the electrical equipment from the back side, so that the electrical connection with the control device at the same time as mounting the electrical equipment Is achieved.
