In a reader-printer having a first optical device for directing a light from a projection lens to a screen and a second optical device for directing the light to a photosensitive medium, the first optical device includes a first mirror for reflecting the light from the projection lens, and the second optical device includes a second mirror movable toward and away from the reflection optical path of the first mirror and movable across the reflection optical path, and third mirror disposed outside the optical path of the first optical device and reflecting the light reflected by the second mirror toward the first mirror. The light reflected by the third mirror is again reflected by the first mirror and thereafter directed to a photosensitive surface.
