Abstract
An emergency disc ejecting device for an optical disc drive including a linkage module and a gear module is provided. The linkage module has a first linkage capable of moving along a disc loading direction and a disc ejecting direction. The gear module includes a first gear, a second gear and a pulley. The first gear is detachably connected to the first linkage. The second gear is driveably connected to the first gear and has a first contacting portion. The pulley is pivoted on the second gear and has a second contacting portion, wherein the second gear has an idle-stroking rotation relative to the pulley. When the second gear performs the idle-stroking rotation relative to the pulley, the first contacting portion moves relatively from a first side of the second contacting portion to a second side of the second contacting portion.
