An automatic film feed device comprises a film threader for automatically feeding, from a film cartridge, a film to be projected, a film stripper pawl for stripping the leading end of the film from the outer convolution of the film roll, and a detector at a film gate to detect when the film has entered the film gate. This detector, upon detection of a film entering the film gate, stops feeding of the film by the film threader, resulting in movement of the film threader and the film stripper pawl to retracted positions. The film threader and stripper pawl perform their functions only when no film is present in the film gate, and responsive to actuation of a projector starting switch.
