摘要： A deterioration sensing device comprises a laser diode (LD), a voltage-current converter supplying electric current to the LD to radiate a laser beam which is received by a photo-diode, and an APC circuit outputting electric voltage in accordance with the intensity of the laser beam sensed by the photo-diode. The voltage-current converter is controlled based on the electric voltage so that the intensity of the laser beam is kept constant. An LD deterioration circuit is provided with a comparator, in which the electric voltage is compared with a reference voltage. An LD deterioration control unit is provided in the LD deterioration circuit to output a deterioration signal when the electric voltage becomes higher than the reference voltage, so that an alarm, indicating that the LD has deteriorated, is output, and the electric current supplied to the LD is decreased.
