  • Patent number: 5060220
    Abstract: A protection circuit for optical disc players which can prevent the unnecessary radiation of laser beams due to a malfunction of the player. The circuit includes a laser radiating and detecting device which detects the laser beams reflecting from an optical disc and a driving stage which receives the detected signal from the laser radiating and detecting device and controls a microcomputer to cut out the supply of a driving voltage to the laser radiating and detecting device when the optical disc is not placed on a disc table.
