Abstract:
A magneto-optical disk recording/reproducing device comprising:a holder rotatably mounted on a base for holding a magneto-optical disc inserted therein and for moving said magneto-optical disc between a disc unloading position and a disc loading position; a turntable arranged on the base for rotationally driving the magneto-optical disc held in the holder that has been moved to the disc loading position; an optical pickup slidably mounted on the base for casting a light beam onto a signal recording surface of the rotationally driven magneto-optical disc; a magnetic head arranged facing the optical pickup on an opposite side of the magneto-optical disc and being movable between a recording position adjacent the magneto-optical disc and a nonrecording position away from the magneto-optical disc; a connection member for connecting the optical pickup and the magnetic head; an ejection lever rotatably mounted on the base and biased toward pressuring and ejecting, by a pressuring portion, the magneto-optical disc held by the holder, wherein the ejection lever is arranged on a periphery of the optical pickup and a main portion of the ejection lever is positioned along the base and a locus of rotation of the ejection lever and a locus of movement of the connection member are different from each other; a lock lever for moving between a locked position for locking closed a cover body for opening/closing the optical pickup and the magnetic head and an unlocked position for canceling the locking; regulating means for moving between a regulating position for regulating movement of the lock lever to the unlocked position and a nonregulating position for permitting movement of the lock lever to the unlocked position; first biasing means for biasing the lock lever toward the locking position; and second biasing means for connecting the lock lever and an operating section with each other and biasing the lock lever toward the locked position, the second biasing means having a greater biasing force than the first biasing means.
