Abstract: A MOTION PICTURE SYSTEM UTILIZING A COMPACT MULTIPURPOSE CASSETTE CONTAINING REEL MEANS FOR TRANSPORTING A STRIP OF FILM ACROSS A FILM GATE AND USEFUL DURING EXPOSURE, PROCESSING AND PROJECTION OPERATIONS. AN APPLICATOR CONTAINING PROCESSING FLUID IS POSITIONED WITHIN THE CASSETTE IN OPERABLE RELATIONSHIP WITH THE EXPOSED FILM STRIP WHILE IT IS BEING TRANSFERRED FROM ONE REEL TO ANOTHER. VARIOUS UNIQUE FEATURES ARE INCLUDED TO INSURE THAT A UNIFORM COATING OF PROCESSING FLUID IS APPLIED TO THE EXPOSED FILM STRIP INCLUDING MEANS FOR SLIDABLY MOUNTING THE APPLICATOR WITHIN THE CASSETTE SO THAT IT CAN BE SELECTIVELY BROUGHT INTO AND TAKEN OUT OF CONTACT WITH THE FILM STRIP, A SELF-ALIGNING SUPPORT PLATE DISPOSED ON THE OPPOSITE SIDE OF THE FILM STRIP FROM THE APPLICATOR, SPRING MEANS FOR YIEDABLY RESTRAINING THE APPLICATOR AGAINST THE FILM STRIP, A NEGATOR SPRING TO PROVIDE A CONSTANT FORCE ON THE PROCESSING FLUID IN THE APPLICATOR AND A MOTOR CONTROL SYSTEM TO IMPART A CONSTANT SPEED TO THE FILM STRIP AS IT CONTACTS THE APPLICATOR. ADDITIONALLY, A FOLDED TAPE IS EMPLOYED TO INITIALLY SEAL THE ORIFICE OF THE APPLICATOR WHEN IT IS SPACED FROM THE EXPOSED FILM STRIP AND WHICH IS AUTOMATICALLY STRIPPED FROM THE ORIFICE AS THE APPLICATOR IS BROUGHT INTO CONTACT WITH THE EXPOSED FILM.
