Patent ID: 7328357

Claim:
A disk reproducing apparatus comprising: a switch to which a commercial power source is supplied, the switch operable to generate a first power and a second power based on the commercial power source; a reproducer operable to reproduce an optical disk in an operating mode; a microcomputer operable to control the reproducer and the switch; and a receiver operable to receive an infrared signal transmitted from a remote controller and outputs data based on the received infrared signal to the microcomputer so as to control the switch, wherein: in the operating mode, the microcomputer makes the switch to supply the first power to the reproducer and to supply the second power to the microcomputer and the receiver; in a standby mode, the microcomputer makes the switch to stop supplying the first power to the reproducer and to supply the second power to the microcomputer and the receiver so as to reduce a load fluctuation of the switch; a voltage of the second power in the standby mode is lower than a voltage of the second power in the operating mode; and the voltage of the second power in the standby mode is in the vicinity of a lower limit in a common range of an operating voltage range of the microcomputer and an operating voltage range of the receiver.
