44, 80, 82, 75, and 90 are connected so that desired power is input from a power supply relay board 140 that relays power supply wiring from the power supply unit board 137. However, power is supplied to the display control board 75 not through the power relay board 140 but through the illumination control board 80. This is the case when the device used as the special variable display device is a drum type variable display member as in the present embodiment, and the case where the electrical variable display member (liquid crystal or CRT) is used.
And so on) use different power supply voltages.
When the type or number of the power supply terminals of the power supply relay board 140 needs to be changed with the replacement of the game board 40, the power supply wiring is branched from the illumination control board 80 that is changed with the replacement of the game board 40, and the display control is performed. When the power is supplied to the board 75, the power supply terminal of the electric relay control board 80 is connected to only the wiring of the required voltage while the type or number of the power supply terminal of the power supply relay board 140 is kept as it is. This is because there is no need to change the type or number of the power supply terminals 140. In addition, the power supply relay board 140 may be separately configured corresponding to the type of the variable display member.

Here, the power supply relay board 140 will be described in detail with reference to FIGS. 3, 4, 7 and 8.
