Abstract
An exposure apparatus has cold mirrors for reflecting visible rays irradiated from light sources and for allowing infrared rays and a part of visible rays irradiated from said light sources to pass therethrough, disposed on a side of a case body. The exposure apparatus eliminates an excessive heat-up at an original image support station by using the cold mirrors and increases a tonality and an effective speed for forming a latent image on a photosensitive sheet with supplementary exposures using a leak of light passed through the cold mirrors.
