PROBLEM TO BE SOLVED: To prevent failure of an electronic component even during power activation, decrease of power source voltage, malfunction of control means, or other case which impedes correct control of the electronic component.SOLUTION: A game machine 1 which allows a player to play a game includes serial-to-parallel conversion ICs 421, 422 which convert a control signal output from a presentation control CPU 120 controlling a rotary motor 403 from a serial signal to a parallel signal and a power control IC 424 which controls supply of operation power for operating the rotary motor 403. The serial-to-parallel conversion ICs 421, 422 include setting terminals which can switch an output logic of a signal to be output, a first transistor circuit which outputs a power supply control signal for controlling the power control IC 424 and a second transistor circuit which outputs an operation signal for operating the rotary motor 403. An output logic of the first transistor circuit and n output logic of the second transistor circuit are the same.SELECTED DRAWING: Figure 17 |
