ABSTRACT:
A film cartridge designed for permanent mounting on a movie projector having an automatic feed mechanism. The cartridge includes a generally rectangular housing for enclosing the entire film reel. A reciprocating spindle is slidably mounted by a pair of pins to captivate the film reel in an approximately precise orientation to permit the automatic feed mechanism to strip the leading edge from the reel and guide the leading edge into the machine. The reciprocal movement of the spindle is accomplished by a cam slot provided in a sliding cover permitting the insertion and removal of film reels without the expense of a cassette for each reel.
