ABSTRACT:
An optical disk handling apparatus for producing controlled linear and rotational displacement of an optical disk received therein comprising: a base member; a guide assembly; a shaft for rotatably mounting the guide assembly on the base member; an optical disk holding assembly received by the guide assembly in linearly forwardly and rearwardly displaceable, rotationally nondisplaceable relationship therewith; a reversible drive motor; a linear displacement assembly for producing relative linear displacement between the guide assembly and the holding assembly; a transmission assembly for transmitting torque from the drive for producing rotational displacement of the guide assembly and linear displacement of the holding assembly; projection members projecting rearwardly from the guide assembly rear end for coacting with a latch assembly; axially extendable and retractable plunger members operatively associated with the optical disk holding assembly and projectable relative the rear end of the guide assembly for coacting with the latch assembly; a latch assembly mounted on the base member for latchingly engaging a projection member during rotation of the guide assembly and for coacting with a plunger member for disengaging the projection member from the latch assembly for enabling rotation of the guide assembly; and a restraining structure operatively associated with the holding assembly for restraining linear displacement thereof.
