Abstract
An ejection structure for an optical disk drive having a tray. The ejection structure is disposed on the back surface of the tray to eject the tray. The ejection structure comprises a base, a motor, a worm gear, a limit switch, a main gear, a first pushing arm, a second protruding pin, a twisting spring, a third protruding pin and a second pushing arm. When the motor drives the worm gear, the worm gear drives the main gear to rotate, so that the first pushing arm and the second pushing arm rotate and move relatively to eject the tray. When the first pushing arm is pushed from the outside of the tray, the first pushing arm drives the second pushing arm to move linearly to eject the tray.
