Abstract: The present invention discloses a disc reading apparatus, including a main chassis, a sub-chassis, a spindle motor, a slide unit, and a stopper. The sub-chassis is movably disposed on the main chassis. The spindle motor is disposed on the sub-chassis for rotating a disc. The slide unit touches the slide unit and selectively touches the spindle motor. The slide unit drives the sub-chassis and the stopper so that the sub-chassis, the stopper, and the slide unit are selectively located at a first status and a second status. At the first status, the spindle motor rotates the disc to be read. At the second status, the stopper stops the spindle motor.
