ABSTRACT:
An optical disc reading apparatus having a reduced overall height and simplified structure. The disc drive motor is mounted with its output shaft extending downward. A turntable is fixed to the output shaft below the body of the motor. A disc carriage is mounted so as to be movable only in a horizontal direction towards and away from the turntable, and a clamper clamps the disc once it has been conveyed by the disc carriage to the playing position on the turntable. A pickup is mounted below the turntable on the side of a loaded disc opposite both the motor and turntable. At least the objective lens of the optical pickup is lowered away from the turntable when the disc is being loaded to allow free movement of the disc toward the turntable.
