ABSTRACT:
In a photographic camera for use with a single-reel magazine wherein the film after withdrawn by a film advancing sprocket for exposure purposes has to be transported backwards to the magazine while the sprocket being idle, a mechanism for releasing the sprocket from braking engagement with a drive member therefor is provided with two control or rewinding buttons arranged to be manually actuable from the outside of the camera housing at respective places, one of which is located in a recess of the bottom panel thereof so that, for example, when a motor drive unit is attached thereto, an automatic responding relationship is established therebetween, and another place which is located so that, while the user is unabled to make use of the first-named rewinding button, as, for example, a tripod remains left in attachment with the camera at its bottom panel, it is made possible to switch the camera from the film winding to the rewinding state.
