Abstract
The invention relates to a film transport and release device for a photographic camera comprising a body part that pulls out and slides in parallel to the film transport direction in relation to the camera body, where in the pulled-out position of the body part the camera is ready to take a picture. Furthermore, a film transport wheel for a perforated film strip is provided. The body part has a toothed rack which is assigned a toothed wheel mounted permanently on a driving arbor arranged in axially movable and non-rotatable manner in the film transport wheel. Here the toothed wheel is movable by means of the release into its ready-to-mesh position in relation to the toothed rack and is kept in this position after operation of the release until the film strip has been transported one picture field further.
