The Clamp Lever slides and lowers the Clamp Arm (the disc is clamped). At the same time, the Roller Up Arm is rotated, and the Rubber Roller is separated from the disc. Also the arm slides the Mechanical Lock Lever, turns the Mechanical Lock Arm, and releases the mechanical lock, completing the clamp operation. 4. When the clamp action is completed, the Clamp Lever rotates the Gear Lock Arm. When the arm is rotated, the Planet Gear is separated from the 2-Stage Gear and engaged with the gear of the pickup feed screw, and the carriage operation will start
