Abstract
A cooling device is provided for a light source in a copying machine, wherein the generation of air seemingly waving due to heat is prevented by effectively cooling a lamp body for lighting an original effectively in order to obviate the deterioration of an optical image. Light pervious heat-shield members are disposed at suitable intervals in an irradiation opening of the lamp body accommodating light source bulb and a reflector therewithin so as to enable blowing of ambient air past and between these members. At least the member positioned at the side of the light source bulb is composed of a heat-ray absorption glass. Air flow is guided through the chamber accommodating the light source bulb so that it may perform a forced air cooling of the inside of the lamp body in order to prevent the generation of the air waving due to heat from the lamp.
