PROBLEM TO BE SOLVED: To provide a game machine capable of securing a time required for power failure processing.SOLUTION: The game machine includes: under-power-failure supply means (a diode bridge circuit 414 and a smoothing capacitor C2) that, when a power supply to a game machine 10 is stopped due to power failure, can supply a guarantee voltage for a prescribed period; performance voltage supply means (DC-15 V generating circuit 413) that generates a performance voltage for supplying to performance means, from the guarantee voltage and supplies it the performance means; and control voltage supply means (DC-5 V & DC-5 V BB generating circuit 412) that generates a control voltage for supplying to control means, from the guarantee voltage and supplies it to the control means. When the power supply to the game machine 10 is stopped due to power failure, the game machine, before the guarantee voltage is lowered to a power failure detection level, stops the supply of the performance voltage to the performance means by the performance voltage supply means and, after the guarantee voltage is lowered to the power failure detection level, stops the supply of the control voltage to the control means by the control voltage supply means.SELECTED DRAWING: Figure 5 |
