Patent ID: 7784066

Claim:
An automatic disc eject device for a disc-loading tray of an optical disc drive comprising: a disc-loading frame ( 10 ), having two pivot holes ( 12 ); a movable disc-loading piece ( 20 ), being disposed on the disc-loading frame ( 10 ); a pivot ( 30 ), having both ends rotatably inserted in the pivot holes ( 12 ), so that movable disc-loading piece ( 20 ) is fixed to the disc-loading frame ( 10 ) through the pivot ( 30 ); a push rod ( 40 ), being connected to the movable disc-loading piece ( 20 ) and capable of fixing the movable disc-loading piece ( 20 ) and the disc loading frame ( 10 ) in a closed position, so as to prevent a disc loaded therein from falling off; a rotary shaft ( 51 ), being connected to the push rod ( 40 ); and a motor ( 50 ), being connected to the rotary shaft ( 51 ); wherein when the motor ( 50 ) receives a signal and rotates the push rod ( 40 ) clockwise, the movable disc-loading piece ( 20 ) rotating counterclockwise about the pivot ( 30 ) to produce a gradient clearance with respect to the disc-loading frame ( 10 ), thus allowing the disc to fall by gravity off the movable disc-loading piece ( 20 ), further that, the motor ( 50 ) driving the push rod ( 40 ) to rotate counterclockwise and making the movable disc-loading piece ( 20 ) return to a original position.
