Abstract
An exposure unit in an image recording apparatus for exposing a photosensitive image recording medium to light is disclosed. The exposure unit includes a light source, and other optical components for directing light to an original and for introducing light reflected at or transmitted through an original to an exposure zone. The light source and the optical components define in combination a light path which has a first light path and a second light path. The first light path extends between the light source and the original and the second light path extends between the original and the exposure zone. An infrared rays non-transmissive filter is disposed at the first light path. Therefore, light directed toward the original is subjected to filtering so that infrared ray components contained in the light is blocked and does not reach the original.
