The control of these winning devices, image display devices and the like is performed by a main board (main control board) having a main control circuit composed of a large number of electronic components such as ICs and LSIs. According to the main control circuit of the main board, the variable display of the image display device is started when the hit ball hit into the game area passes through the symbol operation port. When this variable symbol stops in accordance with a predetermined combination of symbols, it becomes a big hit and a predetermined game value is given to the player, that is, a special winning opening is opened, and a large amount of prize balls are paid out. It is possible.

In such a gaming machine, since there are many pitches (values) based on the jackpot probability generated by the main control circuit of the main board, it is possible to give the player a sense of satisfaction. If the jackpot occurrence probability is set too high, the gambling will be too high.
Therefore, in order to suppress such gambling, inspections such as the probability of occurrence of jackpots are performed before the gaming machines are shipped. This inspection is mainly performed by inspecting the main board, and gaming machines that pass the inspection are shipped.

[0005] However, in the above-mentioned main board, in addition to the main control circuit in the inspection, a lamp control circuit for turning on and off a lamp device provided on the game board and a symbol displayed on an image display device are provided.

[0007] Here, the voice control circuit and the lamp control circuit have a smaller number of electronic parts and the like used than the main board, and can be made smaller in board size than the main board. Accordingly, the size of each shield member provided on the audio control board and the lamp control board can be reduced.

However, when the size of the shield member is reduced, the surface area of the shield member is correspondingly reduced, so that the noise withstand voltage of the sound control board and the lamp control board is reduced, and the electronic components mounted on these control boards are reduced. There has been a problem that the frequency of occurrence of component malfunctions increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a game machine capable of reducing the frequency of occurrence of malfunctions of electronic components for controlling a game and operating them properly. The purpose is to provide.
