Emergency ejection device for a slot-in disk drive

An emergency ejection device for a slot-in optical disk drive, the slot-in optical disk drive comprising a housing and a sliding component, the emergency ejection device comprising:

• a driving motor disposed inside the housing for driving a worm gear;
• a rotating component, a central hole of the rotating component and a first gear engaged with the worm gear being disposed on the housing in a rotatable manner, a sliding slot being formed on an end of the rotating component, a buckling slot being formed on an end of the sliding slot, and a clutching gear engaged with the first gear being disposed on the other end of the rotating component;
• a second gear fixed on the housing and engaged with the clutching gear;
• a locking component disposed on the housing via a hole in a rotatable manner, a sliding column protruding from an end of the locking component and inserting inside the sliding slot, and an inclined surface protruding from the other end of the locking component;
• and
• a spring, an end of the spring being disposed on a lateral side of the driving motor and the other end of the spring being disposed on a side of the locking component adjacent to the inclined surface;
• wherein the spring provides an elastic force for holding the sliding column inside the buckling slot so as to constrain the buckling slot to move in a rotary direction of the rotating component and to keep engagement of the clutching gear with the second gear, and a line of force applying on the sliding column by the buckling slot in a rotary direction of the rotating component substantially is close to a central hole of the locking component when the rotating component is rotated.
