ABSTRACT:
A film cartridge comprises a housing with a film exit slit, and a film roll support rotatable inside the housing to unwind a filmstrip beginning with a film leader to permit the film leader to be moved outwardly through the slit to accomplish film loading in a camera. According to one feature of the invention a protective strip is provided with a length and a width dimensioned to permit the protective strip to completely cover a non-emulsion side of successive frames of the filmstrip when individual ones of the frames are positioned outside the housing for exposure in a camera. The protective strip has a forward end portion releaseably secured to the film leader and a trailing end portion permanently secured to the housing to make the film leader first pull the protective strip onto the non-emulsion side of the filmstrip as the film leader is moved outwardly through the slit and then disconnect from the protective strip as the film leader is moved further from the housing, in order that the protective strip will remain on the non-emulsion side of the filmstrip to shield the non-emulsion side of individual ones of the frames when individual ones of the frames are positioned outside the housing for exposure in a camera. According to another feature of the invention the film cartridge includes a visible film-loaded indicator located on the housing to be seen through a window in a camera, and the protective strip is originally covering the film-loaded indicator but is pulled off the film-loaded indicator when it is pulled onto the non-emulsion side of the filmstrip as the film leader is moved outwardly through the slit.
