ABSTRACT:
An image recording apparatus having a light source which illuminates light to one of a reflection original image and a transparency original image, and an imaging lens system which uses the light reflected or transmitted from the original image after being emitted from the light source to form an image on a photosensitive surface of a photosensitive material. A plurality of light emitting diodes are used as the light source. Accordingly, controlling the current to the diodes allows control of a quantity of light without changing the color. It therefore becomes unnecessary to provide a diaphragm mechanism for the imaging lens system. As a result, the apparatus can be made small.
