Each of the plurality of control boards is provided with a power supply generation circuit, and the voltage (eg DC12V, DC24V) required by each control board in the circuit is generated.
It is pointed out that not only the cost of each control board increases but the miniaturization of each control board is hindered by the configuration for generating the power supply. Further, it is necessary to connect a power supply unit arranged on the upper side of one side of the mechanism set board and a plurality of control boards scattered on the mechanism set board by power wiring.
Depending on the position where the control board is arranged, the power supply wiring becomes extremely long, which makes the wiring process troublesome. Moreover, if the power supply wiring becomes long, noise may be picked up and various electrical parts may malfunction.

Further, in each of the control boards, a power supply voltage for driving an IC circuit such as a CPU or a RAM provided in each board is individually generated. There is a possibility that an error may occur in the power supply voltage for driving the IC circuit generated in each control board due to the individual difference of the above, or the voltage fluctuation of the original power supply supplied from the power supply unit to each power generation circuit. Furthermore, if the above error occurs, it becomes impossible to send and receive signals between the control boards,
There is an inherent defect that the IC circuit itself may be damaged.

Furthermore, it is difficult to make the size of the game machine that can be projected rearward more than a certain size because of the installation space and the like, but the main control board protects the game parts from the cover. Since it is arranged on the back surface of the back cover member, it is necessary to reduce the internal depth dimension (dimension in the front-rear direction) and the vertical and horizontal dimensions by that amount. For this reason, for example, it is difficult to dispose a large game component that largely protrudes to the rear of the game board in the game machine, and it is pointed out that there is a defect in lack of playability and power.
