ことを特徴とするカメラのフイルム給送装置。[Scope of Claim for Utility Model Registration] A rotational drive source, a pre-winding mechanism that pulls out the film stored in the cartridge in advance and winds it onto a spool, and a single-frame winding mechanism that rewinds the film one frame at a time from the spool into the cartridge. a variable focal length mechanism that changes the focal length by extending or retracting the photographic lens barrel; a power transmission mechanism that transmits the rotational force from the rotational drive source to the one-frame winding mechanism or the variable focal length mechanism; and a preliminary volume. a first clutch mechanism selectively connected to the input side of the mechanism or power transmission mechanism to transmit the rotational force of the rotary drive source to the prewinding mechanism or the power transmission mechanism; and a first clutch mechanism connected to the output side of the power transmission mechanism and configured to control the focal length a second clutch mechanism that is selectively connected to the variable focal length mechanism or the one-frame winding mechanism and transmits the rotational force of the rotational drive source to the variable focal length mechanism or the one-frame winding mechanism; In this case, the cartridge fork is movably incorporated in the axial direction inside the cartridge shaft gear constituting the one-frame winding mechanism, and an elastic body is placed between the camera body and the cartridge fork to connect the cartridge shaft gear and the camera body. A film feeding device for a camera, characterized in that a friction is generated between the film feeding device and the film feeding device.
