Abstract
Abstract A photographic camera (426) is disclosed which includes an external housing (428, 478) having at least one movable closure (484) which, in an open position of the at least one closure, enables a discrete strip of film to be loaded from an exterior of the camera into the camera and a discrete film strip to be unloaded from the camera to the exterior; a film guide track (566) extending within the housing between an unexposed film chamber (562) and an exposed film chamber (564), the film guide track having a width corresponding to a transverse width of the film strip; and a mechanism (476, 508, 526, 530) for moving the film strip back and forth in the film guide track between the unexposed and exposed film chambers. The camera uniquely includes a feature (386, 550, 552, 574, 576) within the housing and at an entrance (554) to the film guide track for positioning an external film loading or unloading device (72, 82) for guiding film into or receiving film from the film guide track.
