Abstract
The microfiche projector enlarges the image onto the flat white undersurface of the top panel of the enclosure which has a flat black interior. The viewer sees the image reflected in the adjustable 45.degree. mirror. The apparent image is about 50' in front of the user to reduce eye fatigue. The image is non-directional which allows considerable movement of the user.
