    • PROBLEM TO BE SOLVED: To provide a projector and its components easily discriminating which slide out of one pair of the slides is arranged to face an erroneous direction. SOLUTION: A film slide projector 10 possesses a rail 50 engaged with a carousel 16 in a complimentary state so as to bring a rail surface into contact with the surface of each film slide in the carousel 16. The film facing the erroneous direction is moved by the surface of the rail 50 so as to make a part of the film exposed to the outside of each slot of the carousel 16 for informing that it faces the erroneous direction. The film slide 12 facing a specified correct direction is completely incorporated in each slot. The specified correct direction of each film slide 12 is decided by a cut part engaged with the rail 50. The carousel 16 possesses a wall part 46 forming the slot of a columnar component which is projected from the wall part and whose cross section is rectangular so that the film slide 12 facing the erroneous direction arranged on it is extended by passing a part of the film slide 12 through each aperture for informing that it faces the erroneous direction. A magnetic head generating a detection signal by detecting a magnetic material on the film slide is used together with a processor 26 deciding the direction of the slide 12 and controlling the formation of an image from the film slide.
