Abstract
A film magazine for still cameras of the type comprising a film feed-out chamber, a film take-up chamber and an intermediate portion extending between the two chambers and having a rectangular exposure aperture is provided at the opposite sides of the aperture thereof with guide grooves for allowing the film in the magazine to be pulled out therethrough. The guide grooves are slanted in such a direction as to facilitate the pull-out of the film. In a preferred embodiment of the invention, the slanted guide groove is provided with an engaging projection to be engaged with a perforation of the film so that the perforation of the film may fall into engagement therewith when the trailing end of the film comes to the guide groove.
