ABSTRACT:
A film wind-up apparatus is incorporated in an interchangeable film magazine adapted to receive a film which has a backing paper including a leading end portion. The winding device automatically winds up the leading end portion only after the magazine is attached to a camera having a winding motor, film is loaded in the film magazine, the back cover of the magazine is closed, and a light-shielding plate is removed. Upon completion of the winding operation, a photosensitive portion of the film faces the exposure aperture, and a camera so equipped is ready to make exposures.
