Abstract
A photographic film assemblage including a film spool about which is wound a length of film, a housing for rotatably supporting the film spool such that a leading end of the film may be advanced to the exterior of the housing via a film withdrawal opening or passageway in the housing, and means for protecting the film from exposure by ambient light which passes freely through the passageway. The passageway is constructed such that relative rotation between the film spool and the housing, in a given direction, is all that is needed to move the leading end of the film to the exterior of the housing via the passageway.
