Abstract
A rear/remote-screen projector includes means for alternatively projecting slide images on a remote screen or on a rear screen mounted on the projection housing. The opening of a door in the housing laterally shifts one of the mirrors in the housing without changing the angular orientation thereof thereby allowing the projected image, previously reflected by this mirror to other mirrors and eventually to the integral rear-screen, to pass through the door opening and to a remote screen.
