Exposure system for image recording apparatus

An exposure system for exposing a photosensitive recording medium to a light, comprising:

• first exposure means disposed on the same side of said photosensitive recording medium for applying light to said photosensitive recording medium;
• and
• second exposure means disposed on the same side of said photosensitive recording medium as the side on which said first exposure means is disposed for applying light to said photosensitive recording medium, wherein said first exposure means and said second exposure means selectively apply light to said photosensitive recording medium;
• wherein said first exposure means comprises a first light source movable along said photosensitive recording medium, said first light source applying the light of said first exposure means to said photosensitive recording medium through a first original, and said second exposure means comprises a second light source, said second light source applying the light of said second exposure means to said photosensitive recording medium through a second original, wherein when said second exposure means is applying the light to said photosensitive recording medium, said first exposure means is disposed in a position offset from a path of the light that said first light source applies to said photosensitive recording medium.
