ELECTRONIC APPARATUS
First Claim
1. An electronic apparatus comprising:
- a power supply which converts alternating current (AC) power input from an AC power source to direct current (DC) power to he output;
an AC power switch which is provided on a first AC power input line connecting the AC power source and the power supply and is turned on and off to selectively transmit the AC power to the power supply;
a relay which is provided on a second AC power input line connecting the AC power source and the power supply in parallel with the AC power switch, and receives the DC power from the power supply to selectively transmit the AC power to the power supply;
a switching unit which selectively transmits the DC power output from the power supply to the relay anda controller which controls the switching unit to supply the DC power to the relay if the AC power switch is turned on.

Abstract
An electronic apparatus having reinforced power saving and safety functions, the electronic apparatus may include: a power supply which converts alternating current (AC) power input from an AC power source to direct current (DC) power to be outputted; an AC power switch provided on a first AC power input line connecting the AC power source and the power source and is turned on and off to selectively transmit the AC power to the power supply; a relay provided on a second AC power input line connecting the AC power source and the power supply in parallel with the AC power switch, and receives the DC power from the power supply to selectively transmit the AC power to the power supply; a switching unit which selectively transmits the DC power output from the power supply to the relay; and a controller which controls the switching unit to supply the DC power to the relay if the AC power switch is turned on.

11. An electronic apparatus, comprising:
-
an AC power switch disposed on a first power line to selectively supply received AC power; a relay disposed on a second power line in parallel with the first power line to selectively supply the received AC power; a power supply to receive the supplied AC power from the first and second power lines and to convert the received AC power to DC power; and a controller to receive the DC power and to selectively supply the DC power to the relay to permit the second power line to supply the AC power to the power supply based on the received DC power. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
