英文摘要	PURPOSE:To display predetermined functions in a semiconductor laser by controlling the temperature of the semiconductor laser so as to obtain a preset temperature when the temperature of a dew point is low and keeping the temperature of the semiconductor laser at a temperature as it is when the temperature thereof exceeds the preset one. CONSTITUTION:Laser beams projected from a semiconductor laser 1 are projected to a polygonal columnar rotary mirror 3 through a condenser 2, and laser beams reflected from the mirror 3 are condensed to a condenser 4 and projected to the surface of a photosensitive body 5. In the constitution, the intensity of laser beams reflected from the mirror 3 is detected by a photosensor 6, and the atmospheric temperature of the photosensitive body 5 is detected by a temperature sensor 7. A temperature sensor 8 detecting the density of the laser, a temperature sensor 8' detecting the atmospheric temperature of the laser and a humidity sensor 9 detecting the temperature of an atmosphere are mounted near the laser 1, output signals from these sensors are inputted to a micro-computer 10, and outputs from the micro-computer are added to the laser 1 connected to the computer 10 and a Peltier element 11 positioned near the laser 1, thus removing moisture condensation generated on a laser output window.
