ABSTRACT:
A film slide projector has a rail which engages a carousel in a complementary manner, such that a surface of the rail contacts a surface of each film slide in the carousel. Misoriented film slides are moved by the surface of the rail to expose a portion of such misoriented film slides outside of respective slots of the carousel to indicate such misorientation. Film slides having a predetermined proper orientation are completely contained within respective slots. The predetermined proper orientation of each film slide is determined by a cut-out portion capable of engaging the rail. Alternatively, a carousel may have walls forming slots with a rectangular cross-sectional cylindrical element protruding from a wall to cause misoriented film slides positioned thereupon to have a respective portion thereof extending through a respective open aperture to indicate misorientation. Alternatively, a magnetic head may be used for generating detection signals by detecting magnetic material on film slides, with a processor for determining the orientation of the slide and for controlling the generation of images from the film slide.
