ABSTRACT:
Projector elements for a film projector selectively project an image onto a local viewing screen mounted on the projector housing or to a viewing screen remotely located from the projector. A projector mounted control is coupled to a reflecting mirror pivotable about a vertical axis and to position shiftable objective and condensing lenses to permit convenient single control shifting of the mirror and the lenses for either local screen viewing or remote screen viewing.
