发明名称 Easy-to-load roll-film camera
摘要 A camera of the type wherein a perforated strip of film is unrolled from a magazine in a magazine chamber at one end of the camera body and wound up by a takeup spool in a spool chamber at its opposite end. In order to afford easy loading of the film, the takeup spool is provided with one or more film catcher blades of arcuate cross section each pivotally mounted thereon along one edge extending parallel to the spool axis. The opposite edge of each film catcher blade is spring biased away from the surface of the takeup spool and normally held separated therefrom. Formed on each film catcher blade is at least one projection which, upon rotation of the takeup spool in a predetermined direction, becomes engaged in one of the perforations in the film thereby permitting the spool to wind up the film. The camera is further equipped with a magazine orienting member pivotally mounted on the back cover of the camera body and spring-loaded into engagement with the magazine in the magazine chamber. Upon closure of the back cover the magazine orienting member acts to properly orient the protruding mouth of the magazine in the magazine chamber.
