Abstract:
An optical disc apparatus includes a first electric power source portion to convert a first power source voltage into a predetermined voltage, to be supplied to a part of the optical disc apparatus. A second electric power source, to convert a second power source voltage into another predetermined voltage, is supplied to other parts of the optical disc apparatus. An electric power source observation portion observes voltages of the first electric power source portion and the second electric power source portion so as to release resetting of a system constituting the optical disc apparatus, when the voltages of the first electric power source portion and the second electric power source portion reach respective predetermined voltages.
