A motion picture projector having a housing or casing having one narrow side and one wide side, substantially perpendicular to each other. The film spools are arranged on the wide side. In a first projection position, the housing is arranged upright, resting on its narrow side, with the wide side approximately vertical. To enable projection to take place also when the projector is laid on a wide side, rather than standing upright, a first mirror is swung into position across the beam of projected light rays, and projects the rays upwardly to a second mirror arranged at an opening in the wide side of the housing. A control knob moves both mirrors simultaneously to effective projecting position, and also serves to adjust the exact inclination of the second mirror so as to vary the height of the projected image on the viewing screen at some distance from the projector.
