Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control board protection structure for an electric pachinko machine.

[0002]

2. Description of the Related Art Conventionally, a ball launching device for an electric pachinko machine is mainly composed of an operating handle, a batting rod, an elastic spring connected to the batting rod, and the spring of the spring as the operating handle rotates. An elastic force adjusting mechanism that adjusts the elastic force and an electric motor that elastically moves the batting rod according to the rotation of the operation handle are provided.

An electric motor of an electric pachinko machine is controlled by a control board, and the control board is housed in a board housing box for protection.

[0004]

However, since the board storage box is constructed only for the purpose of protecting the control board from the surrounding environment, it is not easy to assemble the control board to the board storage box. In addition, when the control board is inspected and repaired, the front and back sides cannot be checked unless the board is removed from the storage box, and there is a problem that inspection and repair work of the control board takes time.

The present invention has been made to solve the above problems, and an object thereof is to enable inspection and repair work on both front and back surfaces of a control board without completely removing the control board from the board storage box. It is an object of the present invention to provide a control board protection structure for an electric pachinko machine that can simplify the mounting of the control board in the board storage box.

[0006]

The present invention has been made in order to achieve the above-mentioned object, and provides a control board protection structure for an electric pachinko machine in which a control board for a pachinko machine is housed and protected in a board housing box. , The substrate storage box is divided into a first divided body and a second divided body on a surface that is substantially orthogonal to a control board surface accommodated in the box, and the inside of at least one of the divided bodies is divided into the first divided body and the second divided body. A substrate supporting groove for supporting the control substrate inserted from the opening side of the divided body in a cantilever manner is provided, and the first substrate is supported in the state where the control substrate is supported in the substrate supporting groove.
The gist of the invention is a control board protection structure of an electric pachinko machine in which a divided body and a second divided body are detachably connected.

[0007]

In order to store the control board in the board storage box, the control board is inserted into one of the pair of divided bodies constituting the board storage box from the opening side and cantilevered in the board support groove, After that, it is sufficient to connect both split bodies,
The control board storage operation is extremely easy.

When the control board stored in the board storage box is inspected and repaired, the two divided bodies are separated from each other, and the control board is cantilevered in the substrate support groove of one of the divided bodies. For example, since the front and back surfaces of the control board are exposed, the front and back surfaces of the control board can be inspected and repaired at once without removing the control board from the board storage box.

Further, when the control board is inspected and repaired, it can be inspected without the operator directly touching the control board, which leads to further protection of the control board and is handled larger and more carefully than the control board. The control board can be inspected by holding the unnecessary board storage box by hand, and the inspection work can be performed more easily.
