A flat surface on the back side of the back mechanism plate is preferable as a place to mount the electrical control device. However, on the back side of the back mechanism board, the rear part of the variable batted ball winning device and lamp indicator etc. are protruding, and various gutter such as winning ball collecting gutter and prize ball discharging gutter are installed, so it is difficult to play on a flat place. Very few and limited. Since the electric control device with electronic components is installed in this limited location, the electric control device includes the drive motor of the electric batted ball launcher and ball circulation device, and the electric operating equipment installed in each pachinko machine. Inconveniences such as malfunction or damage have occurred due to electrical noise from outside the ball or static electricity generated in the ball itself or the resin part of the back mechanism plate during the ball's rolling process.

Also, when transporting the electrical control device or installing it on a pachinko machine, the board may be deformed by hitting other equipment.
If the electric control device is attached, the balls in the upper tank may fall out and damage the board. Additionally, electronic components generate heat that, if not dissipated from the board storage device, may malfunction or be damaged.

The present invention has been proposed in view of the above, and includes a special prize opening and a variable hit ball winning device connected to an electric drive source in the game section surrounded by the guide rails of the game board. In a pachinko machine that is equipped with a back mechanism plate on the back side of the board that has the function of processing the balls guided from the above-mentioned gaming section and controlling the flow of prize balls, the electric drive source of the above-mentioned variable hitting ball winning device is At least a first shielding member having a frame shape and a second shielding member having a flat plate-like portion are used to control a board having an electronic component to be controlled.
