ABSTRACT:
In a film rewinding device for a movie camera which is capable of selective use of both the type A magazine provided with a non-releasable anti-backup mechanism on the exposed film take-up shaft and the type B magazine provided with an externally releasable anti-backup mechanism on the film take-up shaft, the film rewinding device comprises a pin to indicate the type of magazine loaded, and for locking the anti-backup mechanism for the type B magazine, to be released when this type of magazine is loaded; a counting gear to count the film footage of the forward or reverse feed, and a connecting gear. The present device makes it possible to selectively use rewinding patterns possessing the advantages of two types of magazines and to employ special photographing techniques for overlaps, superimposition and reverse shooting, in suitable combination.
